For what it's worth, I'm seeing the same issue on a Samsung Galaxy Tab S8: it used to connect automatically, but now I have to go to settings and manually make the connection each time.  It's working OK otherwise.  Android 13, MobileSheets 3.6.9, Google MIDI library.

I'm not sure when exactly this changed, so don't know if it could have been an Android update, a MobileSheets update, or something else.
