Originally reported Nov 25th 2016, still occurring in iOS app Jan 1st, 2017:
In the Device view, trying to switch between devices sometimes requires a second tap of that device for the right panel to display the new device. The first tap results in the device highlight during the touch, showing the touch input was received, but it continues to display the previous device data in the right panel. The problem is non-deterministic and doesn’t have a guaranteed reproduction scenario.
