Error 'The Apple ID is either not valid or not supported' while trying to update apps on my iPhone
I have lost /forgotten the password for an old Apple ID which was changed by me over 10 years ago. When i go to update Apps like Whatsapp and a few others it keeps asking for the password to this account . When i select forgot password, it says' The Apple ID is either not valid or not supported' . I have not been able to use WhatsApp since the last 3 to 4 days and Apple Support has not been able to respond.
