I can see my device (Edge 200) in the Garmin Express program and sync rides from it, but using the "modern" website I am unable to send courses to this device. I get a terse error "No compatible devices found.". If I switch over to classic, I am able to send courses to the device with no problem. Garmin I'm hoping your crew can fix this or at least don't take away classic.
p.s. When creating a course in Modern how come the map only displays on about 1/3th of the vertical space on my screen? Why must half of the screen be taken up by that monstrous footer, and that other footer, and an annoying message box about segments not working, and the normal header? I want the map to cover the whole vertical, please.
