Just installed TB V102.6.1 (64 bit) after being fedup with Outlook 2021 (just updated Office from 2013 to 2021). I decided to use TB instead and am mostly pleased with it. I have a view to my Google calendar in TB. Sync seems to be OK there. But, sync with contacts seems to have some problems. I did click the down arrow on the TB address book, clicked on the "Add CardDAV item". I saw the address book flash on the PC screen and it changed to first name/last name where it had been the other way around. I switched that back. I can update a contact on my phone and see that update pretty quickly on the Google calendar when logged in on my PC. I can update on the PC and see the update on my phone. The trouble is that I do NOT see those updates reflected on the TB address book. From browsing the forums, I can see that others have had these types of problems. Is there an issue with syncing with the Google contacts from TB? This should be a 2 way sync to be of any use.
