No sharing options in NC Mac app anymore

NC app 33.0.5, Tahoe 26.5.1. No sharing options, no Finder integration. Restarted, no dice. No change on my part whatsoever.

Any tips? Thanks!

Assuming you are using the classic synchronization folders, please note this known issue:

This is a known problem and we have not figured out yet how far we can influence macOS to behave as desired and load the FinderSync extension which conflicts with the file provider extension (a problem handed to us by Apple which considers file providers the designated successors to those legacy extensions and does not allow both running simultaneously while macOS has the sole power of choosing what is loaded).
