Was hoping Samsung could chime in and give us some official word like they did in the below link
[OFFICIAL] One UI 4 Official software update
So far only participants in the beta program have been using the update. Samsung has released the stable version in Korea twice - and halted the rollout twice. There are clearly some issues, some of them on Google's end, that need work. I'm sure Samsung will roll it out again once there's reason to believe the issues are resolved.
