Hi.
I have a new Fenix 6s. I copied some 300 songs to my fenix 6s pro with the garmin express app. I had no problems until then. but if I now connect the watch to the computer it connects disconnects and after some minutes it tries to reconnect it also reboots at some time. But it only happens when Garmin Express is running in the background. I notices, that it takes more time until the drive is visible in the explorer maybe because I have copied so many files to it. And garmin express is trying to sync at the same time. I think there starts the problem somewhere. I tried on two computers and it's the same behavior. Hope you can help, because I want to use garmin express to transfer the playlists.
