When test leave application and tries obtain elements tree the issue happens. It reproduces in iPad pro with iOS 10.3.3. I have the same iPad with iOS 11.0 and it works fine with it. I've tried get elements tree with appium desktop UI Inspector but the same issue happens. No matter if home screen is opened or safari.

@marekcirkos could you clarify issue?

[marekcirkos]

I suspect getting source is slow, which is known issue on iOS 11.

This is happening for IOS 9.3.5 for ipod touch with appium desktop version 1.2.6 (1.2.6)

I have a problem with iOS 11, XCode 9 and latest Appium release 1.7.1. I can't get page source to process call kit screen for incoming call. Yes the page source retrieving is slow but even if it finish before call kit disappears, the content of page source is native screen with application icons.There is no Accept / Decline buttons. With iOS10.x and XCode 8.3.3 and Appium 1.6.5 call kit screens can be manipulated as part of the application.

@marekcirkos It seems not the same problem as slow getting source because in app it returns sources.

[shynkevich-alex]

With latest update it reproduces on iOS 11
