Now that I have installed 18.22, the wrist measurement is no longer working. I did a suggested Garmin workout with warm-up today. Same left arm, same clothes, same track, same tightness as always. After 7 minutes I thought the watch had started to recognize my heart rate, but it just got stuck somewhere around 130 and the watch kept giving me "false heart rate alerts". After pausing the workout for a few seconds my correct heart rate of around 155 was recognized immediately. I then did a short test sprint, which was completely ignored by the watch.
Inb4 "use a chest-strap": It has worked perfectly for me so far.
