Hi, I'm running El Capitan version 10.11 Beta (15A278b) and I cannot get the App Store to do anything. I installed this Beta (as with all others) from the app store. Overall I really like El Capitan but this really annoying. I can't search for apps or check for updates. I don't see the "Featured Apps" - nothing. I can't see my "Purchased" history either. It just sits there with an empty window and a little spinning icon in the upper left as if it's waiting for a response from the store. Any solutions I could try? Thanks.
