Ok - as I said I’m not an admin, so I don’t think I would be able to see the settings.
Shall I close/re-open the browser and see what happens?
Update
Looks like this must have been the case. I just refreshed the page, went back in and the list of unread items was slightly different. I clicked on the first topic, it took me to the last post, I used the links to navigate back to the summary of topics and the count had reduced by 1 for the unread items.
Could you change the settings back, I will then point the team to this thread. Is that ok?
(had to put this here as I’ve reached the max number of replies for a new user!)
