Since this morning, I see that the notifications (unread count), isn't getting cleared even after the corresponding notification is read (in fact, I currently don't have any unread notifications). This is definitely not a browser/cookie/cache issue as I tried different browsers. Strangely, I am experiencing this only after the site went "read-only" today and came back online.
Edit: (Below doesn't seem to be relevant to the notifications)
Anyone else noticing the same behavior today?
