I've had my 310xt since 2010 and I'm very familiar with creating and syncing workouts via Training Center and the ANT Agent. I figured I'd get with the program and start transitioning off of TC / ANT Agent and over to GC / Garmin Express but am running into some issues. (Actually I purchased an Edge 810 which of course doesn't support TC/ANT so I figured I'd bring both devices into the same platform instead of managing 2 different sets of apps).
I can sync my completed activities from the device to GC via Express just fine, no problems there. The problems start when I attempt to go the other way, from GC to the device:
1. I create a workout on GC, select "Send to Device", it searches and finds my 310xt. Click "Send Workout". It says "Preparing Workout..." and sits there forever, nothing else ever happens.
2. I create several workouts and schedule them in the Calendar. From within the Calendar I select "Send workouts to device". A window appears and tells me how many workouts will be sent. Click Send. Says "searching for devices" briefly then says it found my 310xt. Click Send. Says "Processing data to write" for about 2 seconds than says "Scheduled workouts successfully sent to device". Yay! Then I pickup up my device and realize they're not there. I'm checking under Scheduled workouts and Custom workouts, which is where my workouts from TC always end up, and they're not there.
Any ideas what's going on? For what it's worth, workouts are syncing to my Edge 810 just fine using the exact same process.
