Sleep data missing partially or completely

In the last 3 days, my sleep measurement has been incorrect (two nights showing 0, and one showing 40 minutes).

Even though my sleep was recorded as 0, I still had scores for RHR and HRV.

U zadnja 3 dana sleep mi mjeri pogresno (dvije noci 0, a jedna 40min)

Iako mi je sleep bio 0, imao sam score na RHR i HRV.
