after last update i cant play , if i try to update game ask to pay for it . i deleted game and now if i try to download asking to pay for game again wt.. i dont know what too do.
I'm not sure how your sim card balance would come into play for updating an app. Go to iTunes and update the app and then download it to your device and see if that fixes the issue. The message you have posted appears that you were attempting to purchase something with an insufficient balance.
In this situation there is an unpaid invoice on your account somewhere. I get this regularly because itunes takes 3 days to debit my account and in that time i may overspend on groceries/fuel etc.
Simply use a pc and go to itunes, log in then view purchase history.
Find the unpaid payment and pay it and you will be set.
If its only localized to castle clash and not any other games you may need to contact apple live support.
Unpaid balances will affect ALL updates.
