Blood oxygen graph incorrect

[JGV]

After the last update, the graph showing blood oxygen is showing nonsense. It's all blue (under 90%), looks like the whole night I didn't have enough oxygen, but the summary says it was only 38 minutes. Data are from my Samsung ring, it used to work fine before.

Hm, how strange.

Could be a case of wiping down the sensors and calling it a day.

*If not, you may need to unpair, reset, and repair the watch to the device.

Could also help with a simple soft reboot of the phone- holding volume down and power until phone shuts down.

Be sure to also submit feedback to samsung members app- support- feedback. As if it is software related samsung can have a look. I imagine if it were others with the ring will comment the same
