Plants vs Zombies 2 problem after recent required iTunes update

I have an iPad Pro 3rd Gen. After the recent required iTunes update for Plants vs Zombies 2 game, one of my Player selections dropped off. I deleted the app and, through iTunes, downloaded again and did this several times. Each time the same Player selection came up for the first round of play, and then disappeared after that. I thought, since the game is in the cloud, that all Player selections and gaming history would automatically download after I deleted the app and downloaded again through iTunes to try and recapture that particular Player and history, but apparently not. I've been playing this game for years and have a long, hard-earned history of upgrades of each plant etc. that I do not want to lose. This is the first time anything like this has happened after a required update of the app...
