There is more:
> A correction was made on Nov. 22, 2023 : An earlier version of this article misstated the status of Carl Erik Rinsch’s series when Netflix bought the rights to it. There was a script, but it was not complete."
'is not complete' can mean many things.
Also Netflix initially planned more than one season, but then they backtracked when the script was extending beyond the first season - there seems to be a gap in the narrative of the article.
> Netflix gave Mr. Rinsch final cut, a privilege it had previously bestowed on only a few directors. And it assured Mr. Rinsch and Ms. Rosés that they would remain “locked for life” to all subsequent seasons and spinoffs
vs
> Mr. Rinsch had missed several production milestones and was toggling between two versions of the script, a shorter one that matched the original 13-episode plan and one twice as long that would have required greenlighting a second season.
Also 'missed several production milestones' is a bit vague. That year we had Corona, which would naturally lead to some sort of delays.
