I've had the correct clockface for several months, but now it says it can't
record SPO2 or I have trouble even getting that clockface to show up. I
originally downloaded it on my iphone and then did a sync. Not sure what
the secret is. Every once in awhile it shows up. For many weeks, when I
awoke, the SP O2 number would be there like 95%, or 96%. It's such an
important number when you're looking at covid, wish I could get it
consistently,
