First, thanks for the help in the forum posts for helping me figure out how to get the Connect Modern app to see both of my Garmin devices when they are plugged into my MBP.
Issue: on the User/Settings/Training page, the "send to device" button does bring up a list box that allows one to select the device to receive the updated zone values; however, only my Edge 800 device is visible.
Configuration:
1. 1st device in Garmin Express is an Edge 800
2. 2nd device in Garmin Express is a Fenix 2
3. Devices are connected to the computer via USB
4. Computer is a MacBookPro10,1
5. Confirmed that connectivity with Garmin Connect by syncing both devices for activities
6. Garmin Express version is 3.2.5.0
7. Browser is Google Chrome (because Safari does not appear to work - this is known problem)
Guess: Looks like a simple list box problem?
