I've been seeing the following more and more lately when I click on the Notifications icon, including when I have new notifications. I sometimes have click on it, or refresh the Notifications page, three or four times before I see the actual notifications. I can eventually get to them, but I figured it important to say something.
To be clear, this is not a major issue for me, and I can eventually get to the actual notifications anyway, so please feel free to put this on the bottom of the pile and help those dealing with more important issues first. 🙂
