I realized that after upgrading to 5.50 when I switch to data screen with map (not during navigation) map orientation is not set to track up.
To be precise on the beginning it is track up but until first stop. When after stop I began riding again it is loosing it track up map orientation. I found simple solution (but not convenient). If I switch to whatever other data screen and switch back to map then it is displayed correctly oriented track up but of course until next stop etc...
Does anyone else found this problem too?
