I recently purchased a Forerunner 255 Music.
However, I cant setup any HIIT workouts. While the watch asks me to download them from Garmin Connect, the App (and Web version) say that the 255 is not compatible with workouts Im trying to upload (both custom workouts and workouts provided by garmin).
Support wasnt able to help me, unfortunately.
Anybody having a similar issue? Thank you very much
