I've been able to add my new 840 Solar using Garmin Express on the PC, but I still can't add it in the Garmin Connect app on iOS. It's just not listed anywhere in the compatible devices.

Is anyone else having the same issue?
I have the same problem: No 840 Solar picture in my web (Safari and Chrome). There was a picture in my app (IOS) but when I remove and re add the device, I lost it too. A triangle logo in my phone and a ? in my web. My 955 and HRM Pro are still there.
