In the iOS app I’ve noticed some glitches with the elevation profiles that I think are caching problems.
I’m not exactly sure how to reproduce it, but I think I’ve seen it when accidentally extending the route to some point along it, producing a roughly mirrored profile, but then it doesn’t get refreshed when I delete the accidental waypoint.
I’ve also seen the profile get out of sync, so one route is displayed with the profile of another, but I’ve been unable to reproduce that.
I’ve attached a screenshot, but I also just noticed that the app didn’t think I was signed in at the time. It could be related, since the routes are private!
Restarting the app seems to force a profile refresh.
