Scifan,
You are talking about iOS Updates and I am talking about the "Installation" program behavior for a new iPad Pro. They may be different. AFAIK, my Pro did the entire install on IOS 10.3.2 and had no progress bars at any time of the four grinding days that elapsed until the Cloud restore finished. After the Install completed, it immediately updated IOS to 10.3.3. I did not watch this update, so there might have been progress bars during the update, too late to be of any use, IMHO.
In any case, there are several problems that are troubling on the Pro.
1. The App Store / Purchased listing shows that many Apps were not installed. No surprise there because some may be having difficulty with 64 bits or new features. However, when I try to manually download some of these from cloud, the App Store displays the downloading circle forever, while the App Store becomes unresponsive until I force a reset on the Pro. Clearly, the Store should display an error message and terminate quickly instead. It should also visually differentiate Apps that had been voluntarily deleted vs those that were not compatible with 64bits, etc.
2. I am wondering why Apple did not offer a software Pro emulation package for those Apps that were not quite ready for Pro prime time. E.g., Khan Academy is not Pro-ready, which will disadvantage students this fall.
EDIT: Correction: Khan Academy IS Pro-Ready but only if you install it directly from the App Store. (If you try to recover from Cloud, the App Store hangs...). When you log on to the Khan App, it remembers you.
To be continued...
