My son has been playing Monster Legends for quite some time now. It's his favourite game, and has put hours and hours into it. I manage his phone through Google Family Link that does not support Google Play Games (no idea why). Now I've given him my hand-me-down phone he has lost all his progress.
I've tried copying all the files and folder found in the folder two location on his old phone to his new phone after installing the game on his new phone. However, the game on the phone phone keeps opening with a the new User ID
How do I migrate this user to another phone without using Google Play Games?
