SpO2 not loaded on my Versa 2

[Zaat]

Today, 23 March 2021, my SpO2 doesn't load on my Versa 2 watch. It says: Sleep to update. But I did!
I've got a premium subscription.

But all my data everywhere is complete, at every device. My online dashboard is filled with last night's sleep pattern. My app in my mobile phone showsthe graphic of the estimated oxygen saturation of last night. There's nothing missing anywhere. Why doesn't show my Versa 2 not the Oxygen percentage of today? And is there any place where I can see these percentages every day, for I want to see my history in this (and they are very important to me).

Does the Versa 2 have an o2 sensor?

Yes, it does. The watch shows daily last night's SpO2 (I think that is the average score , and last night's range.

Sometimes it just skips a day, for unknown reasons.

There's no place where I can view this kind of history.
