The targetSdkVersion needs to be updated to >=33 in order to publish an update on the Google Play Store.
I've checked whether the master branch version of the app runs on an emulator with the minSdkVersion set to 14. I get crashes unless running an emulator running an OS supporting API level 21 or higher. While the app builds, there is obviously some kind of incompatability with older API versions - this might be related to Google Play services dropping support for API level <21 in August 2023. I suggest that the minSdkVersion is updated to 21 to reflect the OS version required to run the app.
