Hi. If you've backed up your progress to your account just before deleting the game, it's okay. (Visit the lost progress setting in the player profile) But don't rely too much on the backup automatically. (When you reload the game).

Probably the old dated backup was restored or the game gave error while backing up (before deleting the game).

you need to pay attention to these. Be sure to back up immediately when deleting and exiting the game.

Have a nice day ☺
