Hey @julian, I couldn't find the setting in a settings page
Am I looking at the right page if I'm going to their profile and then clicking the 'Settings' option?

Okay, so I created a group for specific people which is private and hidden. I have about ten members in it, and only two of them do not have the tag. Does anyone have an idea how this is possible and how can I eventually resolve this and make sure that they, and everyone else which may join the group in the future will get their tags without issues?
