This has stopped working and asking password again ; Can you guide on how to enable Oauth for tbysnc for Thunderbird step by step

This review is for a previous version of the add-on (4.8). 

Remove your account in TbSync and set it up again, this time using the 3rd option (modern auth / oauth).

But, why are you downrating me? And expecting me to help at the same time?
