With my FR 955 Solar, since approx. a week the PulseOx SpO2 stopped working properly.
It worked fine up until last Saturday, 2024-11-24. After I've connected it to the PC and synchronized with Garmin Express (including charging), it stopped.
Then last Thursday, 2024-11-28, I charged it with a USB wall plug, i.e., no USB enumeration. Afterwards it started to record PulseOx SpO2 again. Yaay!
Yesterday, Saturday, 2024-11-30, I again used Garmin Express, and since then it stopped recording SpO2 again.
I checked the exact time, and yes, it always correlates well to the time while it was connected.
My Firmware is 20.32. I use Bluetooth to connect to my mobile with Garmin Connect.
