That might have more to do with HBO Max getting the axe seemingly. Or it could be because Jenkins stretched herself too thin, she wanted to do Star Wars and her own projects, instead of showrunning the Wonderverse. In Hollywood you need a powerful backer to get anything made and if Jenkins wasn’t constantly pushing for it, WB was unlikely to make it. Shame the Dora are going to get a show before the Amazons but if the Dora do well it might convince WB to do something with the Amazons.
