Problem on samsung tab

I have a new device Samsung galaxy tab a9, and after update game I have very more lags, and game is brocken. Please fix this :pray:

I have been trying to buy that game since it’s been on sale for 3 day but I just keep getting error code Ive tried with cards and battle net bucks nothing works no way to contact a human and a robot doesn’t do anything for anyone and the sale is gonna be over soon I’m gonna have a 20 dollar reminder just sitting there on my blizzard account
