I keep checking the members app every few hours just incase it pops up. Sounds like it already has a few bugs since it was rolled out to s10 devices, so maybe the longer wait will help the update to be more stable for all us Noters out there.
Well it's no use. Apparently the registration program was for a limited time only and they have ended it so they can do testing. The full official release of Android 10 wont be for another 2-3 weeks.
You'll be waiting a while. Samsung is notoriously SLOW with updates (unless you're talking about joining the beta program). I wouldn't expect an update to Android 10 before February, but even then they may not do it until after the S11 launches (in a misguided attempt to not.stealnits thunder).
