Hello,
Maybe someone had this problem too and know how to solve it. I recently bought Fenix 5X (upgrade from my good old Fenix 3) and today I tried to sync my training calendar. When I tried to copy more than 15 trainings to my Fenix 5X it won't sync at all. And when I'm trying to sync 15 and less it says "synchronization complete", but on my watch I can see only last training from my calendar... Can someone help me? Firmware 7.60.
