HRM Pro and Fenix 6X Pro, sync failed

Hi all,

I have strange problem and don't know why; The HRM Pro strap is connected with the watch and with Garmin Connect app but syncing keeps failing from 25th of January.

I tried removing and adding back HRM Pro from Devices (and from Bluetooth on the Android phone), I also tried removing and adding the watch from Bluetooth, with no luck.

Software on the Fenix 6 is official Version 24.85 Beta, if this is the problem?

Help please.
