Hello everyone. I just find it is no longer possible to download app updates from iTunes 12.6.4. Does that mean we can no longer keep a collection of iOS apps locally? The iTunes just says "The reported disk could not be found", as if the app is gone from App Store. The app can be updated normally at iOS 12 though. Update: looks like a network problem, either on my side or on the Apple side. Anyway, works again for now.
