I cannot remove groups from favorites. I’ve seen other posts mentioning that favorites from the files.app are mirrored, but this does not seem to be my problem.
I’ve tried looking-pressing on the desired group and selecting “Remove from favorites” as well as batch removing using “Edit” - in both cases the modal appears and informs me the selected groups are being removed, but nothing happens.
I just removed a group from the Favorites global smart group in DEVONthink To Go with no issue. Also, no message appears when you do this. What are you seeing?
