Prepare for upcoming Google Mobile Ads SDK release

The next major version release of the Google Mobile Ads SDK is expected in early 2022. Be sure to follow migration guides closely to avoid potential issues. See detailed migration guides for Android and iOS. 

The Google Mobile Ads (GMA) SDK version 21.0.0 (Android) or 9.0.0 (iOS) will be released in early 2022. In the update to these major versions, a number of existing APIs will be changed or deprecated. Minimum required Android and iOS versions will also be updated. 

Please consider the following:

• Before these versions become available, please consider updating API usage in existing apps per the migration guides below.
• When GMA SDK version 21.0.0 (Android) or 9.0.0 (iOS) becomes available, please ensure all app(s) have been updated according to the migration guides below before releasing your app(s).
• Updating the GMA SDK version 21.0.0 (Android) or 9.0.0 (iOS) without also making changes to the following APIs per the migration guides will cause issues with apps building or compiling and may affect revenue.
• The breaking changes in GMA SDK to version 21.0.0 (Android) or 9.0.0 (iOS) will not break existing implementations that target older SDK versions.

For a full list of changes (including additional breaking changes), refer to the following migration guides:
