You can find a previous discussion about the remix issue here.

Hi, it's 2023 and this still hasn't been resolved. Can we start discussing this again?

I see the netflix s04 remix episodes have been added to the specials https://www.themoviedb.org/tv/4589-arrested-development/season/0/episode/6 which I guess is in error considering the ongoing discussion in the thread linked above from rebecca.

Reposting here as well: Is there any update to this? Can we please get this figured out? I think it would be terrible to cram the remixed season 4 into specials or make it a fully separate show entity. Let's figure out the "4.5" thing and make this happen. This remix was done in 2018. It's been over five years now. I think you all do a terrific job here, but seriously, it's been five years. You cannot even watch the "original" season 4 on Netflix anymore.
