Thanks; this is a usability bug that is fixed in the forthcoming update.

When in navigation mode and the various messages pop up, e.g. warnings about controlled airspace ahead etc etc, the message is full width of the iPhones screen and the red "X" to close the pop up is hidden behind the tabs on the right hand side for the Notams, weather etc making it almost impossible to close the message when in flight unless you can be mm accurate with your finger - not easy in turbulence or when you should be concentrating on something else. See screen dump examples below. Is there a setting in SD I can change ? (Accessibility options / font size in the iOS settings are all set to the default) (I'm using latest versions of SD and iOS9)
