Dismiss button under "Unread" not working

Since a couple of days the “Dismiss” button under the “Unread” is not working.
Observed this behavior using Safari

Firefox, too.

I had the same problem (Firefox and Chrome on Android): find the topics you have set to “tracking”, switch them to “normal”: dismiss button works again.
By the way, you should READ the threads, not dismiss them :grinning:
