Hey @atha.cyanberg,
This is merely a warning and will not block you from submitting an APK. Just ensure all of the potential checkmarks needed are filled and you should be good to go.
However, if you want to make use of AAB’s (which I would recommend doing so if you are on SDK32 or 33), you can follow the information here: https://twitter.com/sjchmiela/status/1140544253627633664
Cheers,
