Heat rate all over the place after 18.22 update!

After I received the 18.23 update, I went for my morning run the following day using my Garmin H10 heart strap. During my base run my watch was reporting my heart rate dropping below the lower threshold, even though I was running at my usual place. This occurred three times, during the run.

I then went for a gentle walk with my wife. My watch was using the optical sensor and it reported a heart rate off 152bpm which is near my lactate threshold during the walk. There is something definitely wrong with this update!

Welcome to the club. The 255/265/955/965 bug forums are full of reports like yours. Garmin didn't give a damn, they released the update anyway.

I've done a soft reset and everything seemed to work ok on this morning's run. I'll keep an eye on it and update if it occurs again.

For me it happened after watch restart as well. I just walked as a warm-up for run session and my HR raised to 120-130 according to watch, while I feel and know it is around 90-100. Then suddenly it dropped to 70 and start to raise again. I used HRM-Pro belt.
