Our team has completed the integration of Google Ad Manager (GAM). The ads are displaying correctly with the test IDs. However, when we use the live IDs we are encountering a "No ad to show" error message.
Below is the error message that we get while using live ID.
AdManagerBannerAd failed to load: LoadAdError(code: 1, domain: com.google.admob, message: Request Error: No ad to show., responseInfo: ResponseInfo(responseId: null, mediationAdapterClassName: null, adapterResponses: [], loadedAdapterResponseInfo: AdapterResponseInfo(adapterClassName: , latencyMillis: 0, description: , adUnitMapping: {}, adError: null, adSourceName: , adSourceId: , adSourceInstanceName: , adSourceInstanceId: )), responseExtras: {})
