I've just spent an hour now on the phone to Apple Education/Enterprise Support. A very nice chap I spoke to in rural Ireland working from home.
First, the guy was able to reproduce the issue on his unsupervised iOS device. On his supervised iOS device he didn't have the issue. Is this the cause then? Is this a hypothesis, that it has to be supervised to work?
But then that hypothesis was broken, as you can see:–
(1) iOS 13 iPod (supervised) DID work.
(2) iOS 12.4.7 iPod (unsupervised) didn't work
(3) iOS 13.5.1 iPhone 11 Pro (unsupervised) didn't work.
(4) iOS 13 iPad Pro 9.7" (unsupervised) DID work.
All tests on latest MBP 16" and latest Configurator (2.12.1) with latest macOS.
So it doesn't seem to be related to what kind of iOS device it is (pad, pod, phone), or what iOS version (12, 13), or whether it's supervised or not (can be either).
So we still don't know what causes this behaviour.
Other hyotheses of mine:–
• too many apps?
• too many folders?
• too many folders?
• does your home screen layout contain web shortcuts?
I have 700 apps, 12 screens and around 5 folders on each screen (50 folders) and 25 web shortcuts.
If folks can check in we might be able to find a common factor that stops it from working on our devices.
If you turn off the passcode on your iOS device temporarily, does that make any difference?
The bloke I spoke to on the phone is escalating his test log to his teams. I'll report back with any updates.
