I haven't seen any good solutions to fixing when attempting to import a .GPX or .TCX file. I created the route in Strava and exported it both ways. The route can be imported into Gaia and it shows up in connect. When I push the done button on either the android or the windows connect app I get the same message. Importing a .GPX that I downloaded from the web from a friend works. It looks like this is a common problem with no clear answer in the forum. Please help.
