I tried 9.0.1-tan to compare it with the latest noop version (ryanbr). And the Whoop app.
HRV, RHR and charge are also not correct and away from Whoop app. Sleep is captured, the stages differ from Whoop app.
I share a straplog.txt and screenshots about the mentioned data for further investigation.
