D2 Air X10 - Pulse Oximeter Data - Erractic Values

Hi,

Just received my new D2 Air X10.

When trying the SPO2 Sensor, I quickly became frustrated. It just shows erratic values.

And yes, all is clean, it's at the right spot, everything is clean, ...

I do have two other watches (Oneplus, Fitbit) and both show a value of 98% which is just 1% off my certifed SPO2 sensor I use (99%).

Just the D2 shows values from 84% up to 94%. This is just crap, and the watch is roughly 3x more expensive.

I wanted to use the watch for flying, but with this sensor readings, I will not use it at all.

Has anyone encountered a similar issue?
