Charge 3 SPO2 tracking in Health Metrics not showing

[AKJOHN91]

I have a charge 3 and started the premium subscription trial to see how the Spo2 tracking worked. My health metrics tab is only showing 3 charts, not the normal 5 listed by fitbit. Specifically, the Spo2 tracking is not available. I can see Spo2 variabillity in the sleep tracker tile, but I was under the impression that i could see actual Spo2 numerical values overtime in the health metrics tab if I purchased the premium subscription.

Hello @AKJOHN91 and welcome to the Help forums.  Here is a link to Fitbit's Help article on the Health Metrics tile.   In the section on available metrics for each device, the Charge 3 lists three: breathing rate, HRV, and RHR.  The Charge 3 doesn't list SpO2 as an available metric.  I have a Charge 4.  The SpO2 section doesn't show any kind of graph.  It gives a single percent number for your average SpO2.
