The ‘Playability’ setting is a bit misleading since there is also another ‘Access Type’ setting under ‘Access Settings’ on the Creator Dashboard, which limits who can join while the experience is public. By chance, did you accidentally toggle that setting to a non-public value?
Even when I access ‘JWZ Main Game’ and set it to public via game settings, roblox still deems it as a ‘group only’ game and this is hindering the public release of the game.
Are there somehow extra settings I don’t know of for making universe places public?
