Manual course upload with .tcx file

Hi,

I've purchased Epix Gen 2 recently and found that this watch doesn't support .TCX file when I tried manually uploading the file into /garmin/newfiles directory.

I've been using this feature since I bought Garmin Edge 500 10 years ago and this feature is the most important feature I need for long distance cycling over 300 miles.

I'd like to know Garmin has a future plan to update it with firmware.

Thanks.
