what Google said here Meet Google Play's target API level requirement | Android Developers
So let me quote the most important parts from that link
Starting August 31 2024:
- New apps and app updates must target Android 14 (API level 34) or higher to be submitted to Google Play
And
You will be able to request an extension to November 1, 2024 if you need more time to update your app. You’ll be able to access your app’s extension forms in Play Console later this year.
Today is July 17th.
So if you get an error and you are not able to proceed, ask Google what is going on and ask them to follow their own rules they defined there
