Your app is affected by Google Play's target API level requirements

I have two apps that have been flagged for not meeting Google Playstore latest API requirements. I have until the end of August to update the App.

I've tried a rebuild, but this did not apply any upgraded API for Android 14.

Deadline
Aug 31, 2024

Violation
App must target Android 14 (API level 34) or higher

Please provide me with the guidance in order to achieve this.
