The problem below still happening and after a month I didn't get any reply on the maps forum. Since the last update the landscape mode is not usable while navigating. The zoom is not correct and it gradually zooms out to the level where I can't se the arrow. When I click the alt route button it zooms out too much I cannot see the routs but the whole country or the continent. After this it's not possible to zoom back and I can't click the recenter button. I don't have this problem in portrait.
