Can't install SpO2 clock face on my Versa 2

[pammyj702]

My new Versa 2 does not have the option for SpO2 (which I need as I have sleep apnea) and there's no update available.  What can I do to activate it?

The required update can take a day or two to become available as it downloads bit-by-bit in the background each time you sync.

I’ve had my Versa 2 for about a week already and the SPO2 app still says it’s unavailable. I signed up for premium just to track this, but haven’t been able to use it yet. It’s been synced and updated but every time I try to download it, it says unavailable.

What version firmware does your Versa 2 have @Salsal2021?

35.72.1.9?

70.7.14? Not sure if I’m looking at the right place. 
This is the number I found when I select Versa 2 under Account.
