I have also just tried the new Modern version of the Connect. I only have one device - Garmin Swim - which is no longer showing up. It keeps telling me that I need to connect my device using Garmin Express - however, Garmin Express already has all the details of my device..... let's hope they get this bug fixed before they switch off the Classic version. If anyone knows of the solution to this problem I would be grateful for the info. Thanks.
