If your new password doesn't get accepted after successfully resetting it, it's either because:
- You're not entering the same password as the one you entered when changing it.
- There's a password manager (like Lastpass or iCloud Keychain) on your device, which automatically enters your old password in the password field.
Please make sure to delete the old password from your password manager and update it to your new password, or to type the new password manually.
