I have a Fenix 6x pro. I used to listen downloaded musics. For the last 3 months I used the Amazon Prime Music with a downloaded list. As I removed the Amazon Prime Music app from my Fenix the original Music Control did not work anymore. I tried several times to upload it using the Connect IQ Store as well as the Garmin Express, but even though it showed it was uploaded, the watch did not respond to any control button. I need help to have the Music Control working back again.
