I'm running the latest iOS9 public beta on my iPhone 6 Plus and the app store no longer loads. The updates section is the only section that shows anything. The other sections (featured, top charts, explore, and search) show nothing. It is just blank pages. In addition, when I go to the updates tab, purchased, not on this iPhone, nothing will install. I click the download cloud and it tries to download and says something like "unable to download app". I have done reboots to no avail. Any suggestions outside of a restore?
