I want to import an activity (running) from an external source in TCX format. I use a Coros watch and I always import my files this way:
My run gps
My training
Import
Then I choose the TCX file and the sport but for 3 days it no longer works.
I added a screenshot to my main message
Do you want to download single activity TCX files? Just checked it and it worked for me. I selected a training and then chose Download as >> TCX. Or do you want to upload TCX files?
