Every time I log in to discourse (I have tried in an incognito window and a few other configurations), the “New” count is inflated by two until I visit the “New” page, here’s a version where I’ve come back after a while and the “New” page was empty:
Possibly this has something to do with categories I’ve muted or something, but it’s fairly annoying. (The “New” notification itself is fairly annoying, I’d really like to be able to turn it off or at least curate more carefully what shows up there, but alas this is pretty clearly a bug.)
It didn’t always used to be this way. I’m not sure how long it goes away for after I’ve visited the “New” page.
