When finishing a ride at night, I often press the button to stop the ride and then turn off my headlight (Garmin UT800). This results in the popup box 'Light network disconnected' appearing on the bottom of the screen, directly over top of the 'save' & 'discard' buttons for the ride. The popup does not go away on its own, and if you tap it it triggers the button underneath. So if you are lucky you tapped the right side of the popup and it will save your ride.
I realize a solution is to always save the ride before turning off the light, but it's silly that a popup would cover up buttons, and even sillier that the popup does not register touches and sends them to the layer below. The popup should behave like it does during a ride, when you just tap it to make it go away.
