For at least the past week I've been unable to download a GPX of my most recent activity. When I attempt to download either a GPX, KML, or TCX file I receive a activity_0.xxx where xxx matches the file extension. Each file has some information within them but absolutely no GPS data. FIT export work as expected.
For example, in activity_0.kml only contains:
<?xml version="1.0" encoding="UTF-8"?>
<kml
xsi:schemaLocation="earth.google.com/.../2.1 ">earth.google.com/kml2.1.xsd"
xmlns:xsi="">www.w3.org/.../XMLSchema-instance" xmlns="">earth.google.com/.../>
GPX is similar. It contains some metadata but no GPS points. TCX contains laps, but no GPS. I suspect this is some kind of Garmin Connect Web processing error of some kind.
