- Ensure that the country/region selected during registration matches the one chosen during login.
- Check if the username is entered correctly; sometimes the registered email or password might be mistakenly remembered.
Verify the registration method used. For instance, if you initially signed up using a social media account, but now you're trying to log in with an email account.
If none of these issues apply and your account still shows as non-existent, please provide feedback for further assistance.
