I'm getting these
SetUp : Xamarin.UITest.XDB.Exceptions.DeviceAgentException : Unable to end session: A task was canceled.
----> System.Threading.Tasks.TaskCanceledException : A task was canceled.
failures on some of my iOS devices on UITest version 2.2.2. The test suite has 30 tests, and on these devices, 2-9 tests will fail because of this error. The tests that fail seem to be completely random and change every time. There doesn't seem to be a trend there. My android devices and other iOS devices don't get this failure, ever. The iOS devices are running on cloned VMs, and are all identical to each other. The devices are all in the same spot and are using identical cables.
iOS Devices with the problem:
iPod Touch 6gen 10.3.3
iPhone 7+ 11.2.2
iPad Pro 11.0.3
iOS Devices without the problem:
iPhone SE 10.3.2
iPad Air 10.0.2
iPad Air 2 9.2
iPad Mini 10.3.3
iPhone X 11.2.1
Any ideas on what's causing this or how to fix it? Any additional information I could provide that would help? It's making test runs on these 3 specific devices completely unreliable. I know this didn't use to be a problem, at least for the iPod Touch since we've had that device for a long time, so I wonder if it's a problem with UITest v2.x.x.
