I recently created a course on my PC and wanted to view it on my tablet. When I downloaded the GCM app, and opened the course, I noticed the elevation gain is 0. This is also true for my other courses. I assume this is a bug, so I decided to report it here.
Some other first impressions of the app.
Only portrait mode, annoying to use on Nexus 10 when default orientation is landscape.
Courses don't have ability to toggle mile markers, or change map type to satellite for example. This appears to be the same when viewing an activity.
I can't seem to figure out how to unlock badges, I have uploaded close to 1,500 activities and still don't have any badges.
Would be nice to be able to create/edit workouts and courses, but I know the app is new and still has a long way to come.
