Hey there! We had run into a few issues with downloading TCX files, so while working on that we decided to switch over to .FIT files since they seem to be the standard these days.
What did you need the TCX files for? I know there’s some online file converters, but that’s not a great permanent solution for you.
Lastly, I think you might have confused GPX with TCX in your post, but it’s not a problem since we’ve never exported GPX files (TR rides don’t have any GPS data).
