the compilation in aab from the play store is buggy when there are mp3 audios, I use the audio for button sounds and it gives an error when I compile in (aab)
Fenix have issues with players. Please wait till it fixes
You should never use a new version of any builder to upload aab or apks to Google Play in the first couple of days. Builders will always have bugs. No software is 100% bugfree. I would advise to wait a few weeks before uploading anything so devs have a change to fix bugs.
