The TCX issue should be fixed now. We can't reproduce the GPX problem though - did you maybe select GPX Route rather than GPX Track?
Thaks for flagging this up Alan. It's odd, as it works OK on a desktop. We'll look into it.
I see a couple of problems downloading files to iOS.
1. If I ask for the TCX file, I get a file named <ride>.tcx.gpx that refuses to copy to Wahoo.
2. If I ask for the GPX file, the file generated is only 2 KB.
The FIT file downloads OK
