The first six-episode season of "The Chosen One" debuted on June 28, 2019, and the second one arrived on December 6 of the same year. Of course, the show hasn't been keeping this schedule up — otherwise, you'd already been able to watch Season 3 and Season 4, as well. So, what's the holdup?
"The Chosen One" Season 3 is currently stuck in limbo. Netflix hasn't officially renewed the show, but hasn't cancelled it, either. As such, there's hope for "The Chosen One" yet, and the fact that Season 2 didn't wrap up the story gives hope that a third season might figure in Netflix's plans, at least at some point. Granted, Netflix has been known to cancel popular shows surprisingly, but the fact that "The Chosen One" hasn't suffered this fate yet could indicate that the platform is waiting for an opportune moment to make the Season 3 announcement. After all, pandemic movies and shows are a potentially sensitive subject at the moment.
Once the good news arrives, hopefully soon, the production cycle of a show like this typically takes about a year. This, and the streaming platform's history of dropping "The Chosen One" seasons on summer or in December, means that the absolute earliest you can probably expect Season 3 is summer 2022.
