I noticed a similar forum post back in April about featured runs maps not working on the mobile app. Apparently there was some sort of bug. I'm still noticing this problem on my mobile app. When I click, View trail on map from the Featured Run it doesn't go to the actual run but instead to the explore map. Was the original bug fixed and this is a new issue or is it still being worked on?
Sorry for the issue. Could you send me a quick email (firstname.lastname@example.org) with a link to the trail or run you are trying to view in the mobile app? I'll take a look at troubleshooting the issue.
