Hi all,
I have this recurrent issue with my 920XT : when I send a course I created on Connect to my watch using wifi, most of the time I get a "Transfer Complete (1 File Failed)" message on my watch.
If I connect it to my computer using the USB connector and Garmin Express, then it syncs without any issue and I can then use the course on my watch.
I've sent an email to Garmin Support but so far no response.
Apparently, it's only the course transfers that fail consistently as I have no issues with activities uploaded from my watch to Garmin Connect through wifi.
Do some of you experience this specific issue with the latest firmware ?
