It seems that Xamarin.UITest 1.3.8 introduced an exception for use when more than one Android device is connected locally.
System.Exception : Failed to execute: /Users/user/Library/Developer/Xamarin/android-sdk-macosx/platform-tools/adb shell pm list packages - exit code: 255 error: more than one device/emulator
Was this introduced with the possibility to mock location on Android M?
I would appreciate it if parallel execution over different devices would be possible again on Android.
Maybe @Glenn.Wilson can help.
