is there any studio settings I can switch around to get my datastore script working?

I have a datastore script that 100% works, but for some reason when I test in studio and give myself cash via the server it doesn't save?? it has to be a setting or something. I have enable studio access to api services checked already.

-- Data storage script

local DataStoreService = game:GetService("DataStoreService")

local myDataStore = DataStoreService:GetDataStore("myDataStore")

game.Players.PlayerAdded:Connect(function(player)
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats"
	leaderstats.Parent = player
	
	local cash = Instance.new("IntValue")
	cash.Name = "Cash"
	cash.Parent = leaderstats
	
	local data
	local success, errormessage = pcall(function()
		data = myDataStore:GetAsync(player.UserId.."-cash")
	end)
	
	if success then
		cash.Value = data
	else
		print("There was an error whilst getting your data")
		warn(errormessage)
	end
end)

game.Players.PlayerRemoving:Connect(function(player)
	
	
	local success, errormessage = pcall(function()
	    myDataStore:SetAsync(player.UserId.."-cash",player.leaderstats.Cash.Value)
	end)
	
	if success then
		print("Player Data successfully saved!")
	else
		print("There was an error when saving data")
		warn(errormessage)	
	end
	
end)
