Many clickbait websites presented the story incorrectly. At Disney+, there were two Muppet TV shows in development, one of which was announced at D23, titled Muppets Now. A second series, tentatively titled Muppets Live Another Day was also being produced by Josh Gad, Adam Horowitz, and Edward Kitsis. This got scrapped however when Gad and Co. walked away because of a change in management at The Muppets Studio. New leadership decided that they wanted to create an entirely new Muppet series that was different from the concept Gad and Horowitz had created and encouraged them to create another idea, but after having worked on this idea for over a year with the previous TMS management and not wanting to throw away a whole year of work, they walked away from the project. This project is only dead because Gad and Co. decided so, not because Disney decided it so.
To recap: The indication seems to be that another Muppet series is still in the works, but the specific one that Gad was working on is dead.
