Proper post with more info of: https://devforum.roblox.com/t/chat-games-are-brocken/3668529/
(I will be referring to LegacyChatService as LCS)
Today was the death date of roblox’s legacychatservice. Roblox seems to have just pushed the update leading to every game using LCS becoming unjoinable and the description failing to load.
Inside these games, it seems that every API has stopped working, datastore service, and more. Leading to alot of these games being unplayable instead of just being broken.
I will continue updating this post as more information releases
