Simple question, I wanna use Data Persistance, but DataReady is never true. Tested it in all of my games, both client and server.
Have you tried a simple script to test it a bit more? Like:
function PlayerEntered(player) player:WaitForDataReady() print(player.Name.."'s data is ready.") end game:GetService("Players").PlayerAdded:connect(PlayerEntered)
