Target API level 31

Ok, do you see something like this (your new app in draft status)? [grafik] If you create a new app and try to upload an AAB, Google will automatically create an app signature (even if the upload fails because of wrong targetSdkVersion (30 instead of 31). So delete the app (draft) by clicking on the delete icon (trash, yellow marked).
