From looks of it it's been put on hold due to serious bug. Something to do with some people with s24 ultra not being able to unlock their phones. I've got s24 ultra and I don't have that problem, could be may time you get the update now depends how fast samsung work and realise a update to people who's already got one ui 7 
hopefully they'll work fast so it can be realised again.
