Yes! Log in with your email, then download Cookie Run again.. everything will be alright if you're switching from Android to Android or iOS to iOS.

It doesn't matter if you are logging in through email, whichever the number you submit after logging in, it's working. But don't register LINE with your new number - it will create a new account instead.
