December Game update applied - lost ant+ HR monitor

Just upgraded this morning. Launched game and My Garmin HR monitor is no longer recognized. I use the CABLE ant+ device with the Zwift Companion app, which was working fine prior to the update.

Companion app version is 3.9.1 / Server version 1.171.2

Hi sneaky,
you may have already done this but I would first change or check the battery.
Second ensure HRM strap is in good condition. (I have just had to change mine.
Even though it looked fine it would not work.)
Lastly I would unpair and pair the monitor again.
Hope this may help.

Thanks for this suggestion.

I ran thru the Cable device setup again. There was a new firmware update available which provides some nice new features. This allowed the solution to work again. So, I’m back in business!


Thanks again.
