If you see an "email already exists" error during registration, it means this email address is already linked to a RedotPay account.
If you're seeing this unexpectedly, here's what to do:
Log in instead. You likely already have an account—switch to the Login screen and sign in with this email.
Reset your password. If you don't remember your password, tap Forgot Password on the login screen to reset it.
If you originally signed up using Apple or Google, the email/password login won't work—use the Continue with Apple or Continue with Google button instead.
