Why isn't load data working correctly?

I have been working on a currency system for my game for a little bit trying to work out the issues. I finally got the save part of the script to work but now the load data part does not work correctly. When I run my test I start the game and press a button that takes away 100 Cash from the player, then I exit the game. The save print says the correct number in the console, however, when I join the game again the Cash value starts back at what it was the previous test. What am I missing here?

local Players = game:GetService("Players")
local CashDataStore = game:GetService("DataStoreService"):GetDataStore("Cash") 

local STARTING_CASH = 100

local function onPlayerAdded(player)
    local playerKey = "Player_" .. player.UserId

    print("User ".. player.UserId.. " Joined")

    local leaderstats = Instance.new("IntValue")
    leaderstats.Name = "leaderstats"
    leaderstats.Parent = player

    local Cash = Instance.new("IntValue", leaderstats)
    Cash.Name = "Cash"

    local myCash
    local success, err = pcall(function()
        myCash = CashDataStore:GetAsync(playerKey) or STARTING_CASH
    end)
    if success then
        Cash.Value = myCash
        print("loading "..myCash)
    else
        print("failed to retrieve data")
    end

end

for _, player in pairs(Players:GetPlayers()) do
    onPlayerAdded(player)
end
Players.PlayerAdded:Connect(onPlayerAdded)

    local savedCash = player.leaderstats.Cash.Value
    print("User has "..savedCash.." in the bank")
    savedCash = CashDataStore:SetAsync(playerKey, savedCash)
    print("User "..player.UserId.." disconnected")

end
Players.PlayerRemoving:Connect(onPlayerLeft)
