Works like a charm with Thunderbird > 78.x syncing my gmail account.

Was using
Cardbook + gContactSync + Provider for Google Agenda

But now
TbSync && Provider for CalDAV & CardDAV

as the previous set was not working anymore or were causing issues in combination with Thunderbird > 78.x

Also more convenient as a I can manage my personal nextcloud calendar & contacts with TBsync as well.
