Backup fail

[steel wigeon]

After changing my phone, installing the game and backing the game up from my previous device, my progress was only 40% of what it was (I've been playing this game for 2 years), there is probably nothing I can do, just curious if anyone else got the same problem /:

Do you still have access to your old phone?

You can simply try transferring the save again
