I am a new vivoactive 3 user, and I am trying to add the hike 2+ app. My phone acts like it has downloaded and installed the app, but I can't see any difference in my device at all. I don't see any new screens. Since I also cannot find a user guide to the Hike 2+ app, only that hikers like it, I don't know what I am looking for or where. How do you find these things out? The user guide gives no guidance and neither does the app store.
