Just took one and works as it always has

I took a couple during the beta phase, with all of my Watches. No problems….

Just did one with no problem. I assume your heart rate was in the normal range and you were not sweating since it has problems with high hr and sweat.

Yep. Normal wearing. Tried over past few days.

Yeah I had a couple of erratic readings since I jumped on the watchOS 8 beta a few weeks ago. I thought at an hardware issue first, but I’m pretty sure that I have these erratic readings since the OS update

I actually figured out mine mostly. I moved my band up a notch tighter and began to get better readings.

Tested it now and it works as always. If it's too loose on the wrist, readings can be inaccurate or missing completely.
