I think that only Xbox players were unable to speak in the chat, because of the limitations of the Xbox, but, I think that Mobile and PC players will be able to speak in the chat, there are several games with this example, re-thinking, I just think.
Yeah, I think players have never really been able to chat on there, apart from MM2, that’s the only game I know of that lets you speak in chat on xbox. I haven’t played on xbox one since 2016 or 2017 though, there may be other games you can speak on, but not many.
Xbox is odd but the reason they don’t have chat is probably that they want Xbox players to use parties and they also don’t want Xbox players to be lured out from Xbox to a 3rd party website. Also because Roblox has an E10+ rating on Xbox from what I believe if they add chat back in it can make their game either unrated or M17+ which would cause Roblox to lose its COPPA seal. I also know that most Xbox games don’t have chats and if they do they are most likely owned by Microsoft who has the resources and systems to moderate messages accurately.
