Recieved an update for the members app and had the banner for the beta registration this morning. Now registered!
So look for an update notification if you haven't been able to register yet, or check the galaxy app store for updates.
US region, unlocked on VZW fyi
Mine may have taken less than 5 mins, but not more. Just keep checking I guess. It all happened so fast, and I was excited so I'm sorry if I'm not super helpful
It's been all day for me now :(. Perhaps it has something to do with my device not being registered with Samsung members. (I can't get it registered and neither could Samsung support)
