The OA Season 3 Release Date. Shoutout to our very own u/night_manager for earning Zal’s respect through diligence, awareness, and endless knowledge be sure to follow @kellybock13 on IG to see more! I think there should be a GoFundMe or Kickstarter for OA season 3-5 because I would throw money at that like nobody's business ! Thus, the next season may or may not take as much time as Season 2.
