Hi gracious, the M2P uses DJI 'GO 4' app.

An A51 runs that app no problem.
Welcome to the forum, we hijacked this thread on the 'FLY' app so maybe a moderator can switch it.
Good luck and have fun!
I just deleted the fly app from my A51, then downloaded and installed the fly apk from dji website. A bubble pops up to the setting that needs to be approved. After that the the app downloads and installs. No issues ever flying with this phone.
I have as well, no problems. I think what you're seeing is after charge, the charger will balance the cells within the battery. It takes a bit more time to complete. It' explains the process in the charger user manual.
