| ## Info messages | Message || |---|---| | $AD_FORMAT $AD_UNIT_PATH not requested: Detected browser is currently unsupported. | **Issue** The specified out-of-page format is not supported on the current browser. *** ** * ** *** **Details** Certain GPT-managed out-of-page formats depend on CSS and JavaScript features that aren't available in all browsers. GPT has determined that the browser attempting to request the ad identified by $AD_UNIT_PATH lacks the necessary functionality to properly render the specified format, ($AD_FORMAT). Applicable to: - `OutOfPageFormat.INTERSTITIAL`
| | $AD_FORMAT $AD_UNIT_PATH not requested: Format currently only supported on mobile. | **Issue** The specified out-of-page format can only be displayed on mobile devices. *** ** * ** *** **Details** Certain GPT-managed out-of-page formats are only supported on mobile devices. An attempt was made to request the ad identified by $AD_UNIT_PATH from a non-mobile device. As a best practice, GPT-managed out-of-page formats should only be requested on pages or environments where you want an ad of that type to appear. Support for additional devices and environments may be added in the future. Applicable to: - `OutOfPageFormat.BOTTOM_ANCHOR` - `OutOfPageFormat.TOP_ANCHOR`
| | $AD_FORMAT $AD_UNIT_PATH not requested: Format currently only supports portrait orientation. | **Issue** The specified out-of-page format can only be displayed in portrait orientation. *** ** * ** *** **Details** Certain GPT-managed out-of-page formats are only supported when the width of the viewport is less than its height (portrait orientation). An attempt was made to request the ad identified by $AD_UNIT_PATH on a page where the width of the viewport exceeds its height (landscape orientation). Applicable to: - `OutOfPageFormat.BOTTOM_ANCHOR` - `OutOfPageFormat.TOP_ANCHOR`
| | $AD_FORMAT $AD_UNIT_PATH not requested: Frequency cap of $FREQ_CAP has been exceeded. | **Issue** The specified out-of-page format has been shown the maximum number of times for the current user within a short period. *** ** * ** *** **Details** Certain GPT-managed out-of-page formats use frequency capping to limit the number of times a single user can be shown the same type of ad within a fixed timeframe (usually 1 hour). An attempt to request the ad identified by $AD_UNIT_PATH was blocked, since the user has been shown an ad of the specified format ($AD_FORMAT) the maximum number of times ($FREQCAP) for the current frequency capping period. Applicable to: - `OutOfPageFormat.INTERSTITIAL`
| | $AD_FORMAT $AD_UNIT_PATH not requested: The viewport exceeds the current maximum width of 2500px. | **Issue** The viewport exceeds the current maximum allowed for the specified out-of-page format on the current device. *** ** * ** *** **Details** Certain GPT-managed out-of-page formats are only supported when the width of the viewport is less than a predefined maximum value. An attempt was made to request the ad identified by $AD_UNIT_PATH on a page where the width of the viewport was greater than this maximum value. The maximum width specified in the body of this message is a default used by GPT in most circumstances. The exact maximum width for a given format may vary slightly depending on the device and environment in which the format is requested, and is subject to change without notice. Applicable to: - `OutOfPageFormat.BOTTOM_ANCHOR` - `OutOfPageFormat.TOP_ANCHOR`
| | $FORMAT $AD_UNIT_PATH not requested: Unable to access local storage to determine if the frequency cap has been exceeded due to insufficient user consent. | **Issue** Local storage cannot be accessed to determine if the frequency cap for the specified out-of-page format has been exceeded due to insufficient user consent. *** ** * ** *** **Details** Frequency capping requires access to local storage in the user's browser to store how frequently an ad of the specified format ($AD_FORMAT) has been shown. An attempt to request the ad identified by $AD_UNIT_PATH was blocked because GPT is unable to determine if the current frequency cap has been exceeded, due to a lack of user consent to access local storage. Applicable to: - `OutOfPageFormat.INTERSTITIAL`
| | An IAB Global Privacy Platform (GPP) Consent Management Platform was detected. Interaction with this CMP failed. User consent decisions may not be correctly respected. | **Issue** An attempt to retrieve consent signals from an IAB Global Privacy Platform Consent Management Platform failed. *** ** * ** *** **Details** GPT detected the presence of an IAB Global Privacy Platform Consent Management Platform (CMP) on the page, but was unable to retrieve consent signals from it. Due to this, ad requests will not contain Global Privacy Platform consent signals. Review your CMP implementation to ensure it is properly configured and responsive. | | An IAB US Privacy Consent Management Provider was detected, but was unresponsive. Please review USP integration to ensure an optimal setup. | **Issue** An attempt to retrieve consent signals from an IAB US Privacy Consent Management Platform failed. *** ** * ** *** **Details** GPT detected the presence of an IAB US Privacy Consent Management Platform (CMP) on the page, but the provider did not respond within 500ms. Due to this, ad requests will not contain US Privacy consent signals. Review your CMP implementation to ensure it is properly configured and responsive. | | Attempted to collect Prebid metadata but window.pbjs.getEvents is undefined. | **Issue** Attempted to collect Prebid metadata but `pbjs.getEvents` was undefined. *** ** * ** *** **Details** GPT attempted to call [`pbjs.getEvents()`](https://docs.prebid.org/dev-docs/publisher-api-reference/getEvents.html), but the function was not defined. This is required for the header bidding trafficking feature to work properly, see [Header bidding trafficking FAQ](https://support.google.com/admanager/answer/12270263) for more information. | | Calling this method may reduce the likelihood of signals being included in ad requests for the current and potentially later page views. Due to this, it should only be called when meaningful state changes occur, such as events that indicate a new user (log in, log out, sign up, etc.). | **Issue** A call to `googletag.secureSignalProviders.clearAllCache()` was made. This may reduce the likelihood of signals being included in ad requests and should only be used in situations that indicate a significant change in the user's state. | | Creative content has successfully rendered after being delayed due to slot element not being attached to the DOM. | **Issue** An ad slot which was previously unable to render due to its container not being attached to the DOM has successfully been attached and rendered. | | Encountered the following error while attempting to collect Prebid metadata: $ERROR. | **Issue** There was an error while collecting and processing Prebid metadata. | | Lazy loading is not supported for Side Rail formats. Invocation will have no effect. | **Issue** Lazy loading is not supported for Side Rail formats. | | Legacy browser does not support intersection observer causing lazy render/fetch as well as viewability events not to work properly. | **Issue** Legacy browser does not support intersection observer. *** ** * ** *** **Details** GPT has determined that the current browser lacks support for the [Intersection Observer API](https://developer.mozilla.org/en-US/docs/Web/API/Intersection_Observer_API). This API is used by certain GPT features to determine the visibility of ad elements. Without access to this API, these features will not work. Applicable to: - [`events.ImpressionViewableEvent`](https://developers.google.com/publisher-tag/reference#googletag.events.impressionviewableevent) - [`events.SlotVisibilityChangedEvent`](https://developers.google.com/publisher-tag/reference#googletag.events.slotvisibilitychangedevent) - [`PubAdsService.enableLazyLoad`](https://developers.google.com/publisher-tag/reference#googletag.PubAdsService_enableLazyLoad)
