Yes, there’s a screenshot here. Those have been muted for nearly as long as Plex has been using Discourse, but this behavior is recent. As noted earlier, it occurs with multiple browsers on multiple OSes, and the behavior is routinely reproducible, as described in the first and second posts in this thread.
You can force the situation by clicking ‘Dismiss New’ inside any forum category. I just did the following:
- Logged into a second account (this account has NO muted categories). It showed 55 new messages at the top of the forum home page.
- Clicked on a category that had around a dozen new messages.
- Clicked ‘Dismiss New’ inside that category.
- Clicked on the Plex logo to return to the home page. The ‘New’ count at the top was now ‘2’.
- Clicked on the ‘New (2)’ link. The New page listed over 30 new messages.
- Clicked on the Plex logo to return to the home page. The ‘New’ count at the top was now ‘New (33)’. (33 is approximate. I don’t remember the exact number).
