Maybe you can try this way:
1. Install the original apk version and log in using google, or you can transfer data if you already have one.
2. Close the game,open file explorer. Go to android > data > and back up the folder named com.bandainamco
3. Uninstall the original version and install the moded APK.
4. Replace the data folder with the one you backed up earlier.
This method worked for me in the previous version, and i think it should work for the latest version too.
Alternatively, you can back up files whose name start with ecd1 and 2b7 then repalce them in the modded data( i haven't try this yet, it's just my speculation lol).
