MapView does not work within ViewLoop

            Adding A MapView as one of the views of a ViewLoop does not work properly on my Fenix 6 v25.00 (SDK 4.2.4): the map is not drawn (DC remains transparent, I.e. it still shows whatever was on view before switching to the map view). Anything I draw within onupdate myself is shown properly. Same behavior on sim and device. The mapview works properly when used outside of a viewloop.
