So while I was charging my epix 2 I was wearing the HRM Pro strap. But after syncing everything I still see a black hole on my watch.
On Garmin Connect the heart rate was correctly uploaded.
I thought, maybe after my march/run (during which my HRM Pro Strap was connected to the watch) my epix 2 will update Heart Rate Data from the morning, but it isn't the case.
How can I correctly, sync those data between my strap and my watch?
HRM Pro v. 8.80
epix 2 v. 10.44
