Tags in tag groups that have permissions set to everyone were not able
to be saved correctly. A user on their preferences page would mark the
tags that they wanted to save, but the watched_tags in the response
would be empty. This did not apply to admins, just regular users. Even
though the watched tags were being saved in the db, the user serializer
response was filtering them out. When a user refreshed their preferences
pages it would show zero watched tags.
I did notice something that isn’t great for my use-case, but is probably intended:
When I make the Tag Group visible to only a specific group, the tag does not appear in the watched list of those who can’t see it (nor does it apply). I used to use the tags to ‘bump’ the topics up to a higher watching state without regular users being able to see it. I can’t do that any more but that is fine.
