Just noticed there's an update available.
Changes made from version 2.40 to 2.50:
Addressed issue which can cause wrist heart rate to remain on a fixed value.

Oddly enough mine did the same. After an hour or so, mine went back to the 71/72 reading when I accessed the widget. I hope you have different results.
Mines gone back now. Starts off low then jumps to 71. Sometimes it stays there for a bit, and sometimes it doesn't. I've had a few weird spikes up to around 130. If I keep checking evry says 30 secs or so its ok, but if i leave it for a few minutes and check again it goes straight back to 71

I see exactly the same behavior. Initialization with 71 or 72bpm, only with subsequent measurement a few seconds later with reasonable values. Also implausible spikes in the 130s or 140s while sitting or walking around.
