Contacts categories not synchronized

[razorrazor]

In the past, I used CategoryManager addon in order to synchronize my NextCloud CardDAV server groups and been able to send emails to a category and so on.

With the new version of TB (v. 100 and higher), CategoryManager is not compatible any more.

I tried to add an Address Book based on a NextCloud CardDAV server, and it was detected in TB 102 and synchronized without third party addons (like "Provider for CalDAV & CardDAV" and "TbSync"). But I realized that existing contact groups in server are not synchronized. However, contact groups in my Gmail account are synzhronized without any problem.

Anybody can help me? Thanks in advance
