Even SPO2 clockface was installed and the first few days was working well, however it wasn't working suddenly. Other health feature is still working on the clockface .only SPO2 feature shows recording and nothing is displayed after sleep to record properly.
Therefore premium health metrics coudn't show any result of SPO2 during my sleep.
if give further more information, this function is not working when this clockface is changed by fitbit app. however, it is working well by direct change on the fitbit versa watch.
and rebooting is another way to wake it up,too. thanks.
