Don’t know if anyone else has noticed this, but for the last few (days, weeks?) at the bottom after I have read all the unread posts - or dismissed the ones I don’t want to read - that it still says “1 unread”. If I click on that link, however, nothing shows up. So that message is spurious.
This is happening on my computer, phone and pad, so it is not OS related. Can try and capture a video when it happens if nobody else has seen it.
