Anyone else having your HRM values jump around a lot? During running it can go from 120bpm to 149bpm for a minute or more, then jump down again. Sometimes I have to deattach my H10 polar and it instantly jumps down 15-25 beats when it reconnects.
I tried my HRM Tri today but same behavior. My H10 does not produce this phenomenon on my 530 Edge.
it also feels like other sensors go up/down in values. Then it gives a lower avg HR when I save my run.
I’m on 12.23 FW
