I had this problem before when I was using Firefox where the store wouldn't load. Now I'm having it again on a different browser. The wheel will spin like the page is loading, but nothing will happen. It worked when I first started using this browser, but not anymore. Could adblocker be causing this?
Possibly, try disabling adblocker on the page, refreshing it and seeing if it works. It could be a false positive or something, double check the other extensions that you have running as well. If that doesn't solve it, try clearing your browser cache
