I can edit an activity in my browser, and change activity type to (f.ex.) Water Sports -> Whitewater or Other -> Motorcykling. But I can't get it so I can have these two types as favorite activities. I tried to add them from the watch (Epix Gen2) and from the Android. But they don't show up at all. Several other sports show up, Kayaking, so I start paddling as Kayaking and then I change activity type in the browser to Whitewater. But why can't I find them directly from the watch?
