Very useful app, but lately NONE of the app's tabs load to let me know if my shop received any updates. Every time I go to the app, I'm automatically hit with "Uh oh, there was a problem." I recently received a message from someone over the weekend asking about one of my listings, and just made a sale today on another listing; I received no notification for these, and would have potentially gone longer without knowing had I not happen to check my email for any updates at the time.
