Navmii was selected from the Store for installation. The app showed as "installing," but it doesn't show up in apps screen, or in downloads. Tried it several times. I even did a restart. No help. ??

I once read that the Surface Pro 4 will come with a compass, but in the technical data I can't find it. Will a compass be included? I'm very much missing it in my Windows Mobile Phone for navigation. The phone always advises to head to some freakingly wrong direction at the beginning of a route.
