[HELP NEEDED] Google Play Warning – App Inventor apps must target Android 15 (API 35) by August 31, 2025

We are in the process of upgrading App Inventor. Until our August release goes out there is nothing to do. Once the release is available, simply rebuild your app and upload a new release to Google Play Store.
