Nearly activated O2 function on updated Apple Watch, while iPhone is in public beta 3 release

I updated my watch to take advantage of the reactivated blood oxygen/O2 function, but with my iPhone on public beta 3, it still shows unavailable. Will there be an update to beta three to allow this newly reactivated Apple Watch feature to function?

Siri messed it up, I missed it in posting, should have started with "newly", not "nearly".
