HRM problems since v12

Hi,

Does anyone else have problems with hrm strips after V12? With V13 and V13.30?

I´ve got 2 strips, one from Garmin another from Geonaute (Decathlon) and both are giving awful readings during exercices (indoor cycling). Or they give very low readings (in heavy efforts 40% to 60% of FCM or they give reading above 100% of FCM.

Change batterys and with my Garmin Edge 1030 the strips both woks fine.

Another question is, it´s easy and safe to downgrade to V12?

Thanks...

Replace battery on HRM strap.

No problems with fw12.0

Delete them from the paired sensors list, then add them back again.

Exactly the same problem on my side. It don't comes from the HRM as i use 2 different one and problem appears with both.

Like i thought... the problem should be with the software version because until V12 never had this kind of problems... And like I sad with the Edge 1030 both straps work perfectly

Yes, same problem! I even bought an original Garmin strap. It's slightly better but not as it used to be.
