I’m bummed too but I also watch Miraculous Ladybug which has taken 15 months to air 26 episodes for literally most of the show, so waiting a few months for the next 4 episodes of invincible is nothing. Especially since the next season of Miraculous is supposed to start airing a whole year from now which actually means probably March 2025 so season 6 will finish airing July 2026.
