Hello there,
When I go to Activity Navigate -> Saved -> choose a trip -> Do Course -> Run or Walk or hike -> Start
and then swipe to the right to see all Navigation Information like
-Timer
-Distance Remaining
-ETA
-High level
the first screen appears in white Backround Color, the second one in black backround color and the 3rd one again in white backround.
I have all my activities in black baclround, also Navigate, so I think this is a bug.
