It's been working intermittently for me too. Been two days now. For me it's been the reset of posts that have been read. Sometimes it won't clear out the posts. When you go back to Favorites after having read a bunch of posts it still shows the posts you just read as new. But when you click on them it takes you to the next board listed in my Favorites. If I try and use reset All it won't clear them, but after hitting the reset if I then click on Favorites than they all go back to zero.
The Hub has some gremlins in it!!!!!
I recently got a new camera. It's so advanced, you don't even need it.
