Datastore data isn't saving when the player leaves?

I have recently watched a tutorial on how to use the datastore service on roblox, but it doesn't really save correctly. (It prints the error message on that it failed to save when a player leaves.)

Here's my code:

local DataStoreService = game:GetService("DataStoreService")

local myDataStore = DataStoreService:GetDataStore("myDataStore")

game.Players.PlayerAdded:Connect(function(player)
	local stats = Instance.new("Folder")
	stats.Name = "stats"
	stats.Parent = player
	
	local valuetwo = Instance.new("BoolValue")
	valuetwo.Name = "two"
	valuetwo.Parent = stats
	local valuethree = Instance.new("BoolValue")
	valuethree.Name = "three"
	valuethree.Parent = stats
	local valuefour = Instance.new("BoolValue")
	valuefour.Name = "four"
	valuefour.Parent = stats

	local data2
	local data3
	local data4
	local success, errormessage = pcall(function()
		data2 = myDataStore:GetAsync(player.UserId.."-two")
		data3 = myDataStore:GetAsync(player.UserId.."-three")
		data4 = myDataStore:GetAsync(player.UserId.."-four")
	end)

	if success then
		valuetwo.Value = data2
		valuethree.Value = data3
		valuefour.Value = data4
	else
		print("data failed to load")
		warn(errormessage)
	end
end)

game.Players.PlayerRemoving:Connect(function(player)

	local success, errormessage = pcall(function()
		myDataStore:SetAsync(player.UserId.."-two",player.stats.valuetwo.Value)
		myDataStore:SetAsync(player.UserId.."-three",player.stats.valuethree.Value)
		myDataStore:SetAsync(player.UserId.."-four",player.stats.valuefour.Value)	
	end)

	if success then
		print("player data saved")
	else
		print("oh no data save failed")
		warn(errormessage)
	end
end)
