In group messages, the “Mark as Solution” button—provided by the discourse‑solved plugin—is no longer visible to users who previously had access to it. The button still appears correctly in topics:
Are you saying it used to work for you in group personal messages? I have not seen that before and thought it was not possible, as per this other topic:
Interesting, based on that topic asking to offer the solved/unsolved filter in inboxes, I would expect the user was already using the solved plugin in inboxes. So I assume it worked when the feature was requested. Why do you conclude that it didn’t work at all?
Agreed. I don’t see how it can be enabled for group messages. Maybe that was a topic that was solved, and then converted to a message? What happens in that case?
