every day or so (usually while trying to update apps) everything gets weird, and all of the built in apps simply refuse to load. App updates stall at like 99.999999% (a completed circle, but still with the border around it). The only way to resolve it is to turn the phone off and on again. It happened both before and after 11.0.1, and didn't happen to me at all on iOS 10. Anyone else? I'm using an iPhone 7.
