The current version of Telegram X on Android doesn't let users reset their account if they forgot their Two-Steps Verification password and can't access the recovery email (not set or lost access).
The window indicating that the user should remember their password or reset their account pops up. Nothing else appears.
The aformentionned message should pop up, and in addition a new button Reset account should appear behind it, to initiate the account reset.
Any Android device.
