Yup - same here. Email from Google yesterday copied below. I’m always dismayed to get these emails. Still, any news on what the latest SDK is and when it’s due for an update?
Just to say, my app was last updated March 2022.
Upcoming Google Mobile Ads SDK version sunset
Please update your Google Mobile Ads SDK to the latest version to avoid revenue impact
Dear AdMob Developer,
You are receiving this email because you have AdMob traffic currently running on versions of the Google Mobile SDK that are slated to sunset on June 30th, 2023. Per the Google Ads Developer Blog announcement in April, we plan to sunset major version v19 on Android and major version v7 on iOS.
What does this mean?
Starting June 30th, 2023, you may notice some disruptions in your ad serving on sunset SDK versions (major version v19 on Android and major version v7 on iOS). Moving forward, ad serving using a sunset SDK version may be reviewed and disabled after this date. Therefore, ad traffic from sunset SDK versions will be at risk of receiving automatic no fills due to stopped ad serving. Additionally, sunset SDK versions will be marked “Outdated” on the Google Play SDK Index, requiring you to update to a supported version for future releases of your Android apps. See this article to understand issues with your app’s third-party SDK for more information.
To avoid disruptions in ad serving, we highly recommend updating your SDK version to the most recent version of the Google Mobile Ads SDK.
How can I update my SDK version?
Please see the Android migration guide or iOS migration guide for more information on how to update.
Why should I do this?
To avoid disruption in ad serving, we recommend updating your SDK to the latest version. In addition, updating your Google Mobile Ads SDK on iOS to version 8.3 and above will provide you access to the same app key. For AdMob publishers, we’ve seen an average of 31% ad revenue lift on iOS – where the Identifier for Advertisers, or IDFA is absent – from app developers who have adopted the Google Mobile Ads SDK 8.3 or later version.
