Well I tried to login my I'd from 2yrs ago in iOS . It was created in android. I found out the it is not possible to login but I had already sign-in that I'd in iOS but it didn't load as expected and when I try to login the same I'd in android it doesn't load and now it shows data connection error and game doesn't even open when restarted but when I try to log in another account it logs in . I don't know what the problem is but please solve the problem .
