Blank app store
The "App Store" app, under "Purchased", for both "All" and "Not on This iPhone", displays a blank screen. This was not always the case when I installed iOS7. I have tried several times, rebooting the phone, to no avail. Is simply "waiting for it to resolve itself" (e.g., via Apple update) a viable approach? Or do I need to go hard-core and restore the phone from backup? (And is this something that occurs often, and to others? I've seen mention of it in other forums.)
iPhone 4S, iOS 6.0.1
