Giving coins gamepass that doesn't work?

This is the script in ServerScriptService

game.StarterGui.ResetPlayerGuiOnSpawn = false
old_fog = game.Lighting.FogStart
local MarketplaceService = game:GetService("MarketplaceService")

function getPlayerFromId(id)
    for i,v in pairs(game.Players:GetChildren()) do
        if v.userId == id then
            return v
        end
    end
    return nil
end

MarketplaceService.ProcessReceipt = function(receiptInfo)
    local productId = receiptInfo.ProductId
    local playerId = receiptInfo.PlayerId
    local player = getPlayerFromId(playerId)
    local productName 

-------------------------------------------------------------------

if productId == 958879047 then
    local Coins = player.leaderstats:FindFirstChild("Coins")
        if Coins then
            Coins.Value = Coins.Value + 1000
        end

-------------------------------------------------------------------

elseif productId == 958879379 then
    local Coins = player.leaderstats:FindFirstChild("Coins")
        if Coins then
            Coins.Value = Coins.Value + 5000
        end

-------------------------------------------------------------------

elseif productId == 958879657 then
    local Coins = player.leaderstats:FindFirstChild("Coins")
        if Coins then
            Coins.Value = Coins.Value + 10000
        end

-------------------------------------------------------------------

elseif productId == 958879909 then
    local Coins = player.leaderstats:FindFirstChild("Coins")
        if Coins then
            Coins.Value = Coins.Value + 25000
        end

    -------------------------------------------------------------------
    elseif productId == 958880690 then
    local Coins = player.leaderstats:FindFirstChild("Coins")
        if Coins then
            Coins.Value = Coins.Value + 50000
        end

    elseif productId == 958881104 then
    local Coins = player.leaderstats:FindFirstChild("Coins")
        if Coins then
            Coins.Value = Coins.Value + 100000
        end

    elseif productId == 958881905 then
    local Coins = player.leaderstats:FindFirstChild("Coins")
        if Coins then
            Coins.Value = Coins.Value + 500000
        end

    -------------------------------------------------------------------
end
return Enum.ProductPurchaseDecision.PurchaseGranted     

end`

This is the script in the ShopGui -> Buttons -> (All the buttons ID) with this in the gui folder

for i,v in pairs(script.Parent.Buttons:GetChildren()) do
    if v:isA("TextButton") then
        v.MouseButton1Click:connect(function()
            pcall(function()
                if v:FindFirstChild("Pass") then
                    game.MarketplaceService:PromptPurchase(game.Players.LocalPlayer,tonumber(v.Name))
                else    
                    game.MarketplaceService:PromptProductPurchase(game.Players.LocalPlayer,tonumber(v.Name))
                end
            end)
        end)
    end
end

It actually worked yesterday but now it doesn't. I have no idea why. When you click +1000 coins ingame the gamepass / product pops up but when i buy it it doesn't give anything as it did yesterday. Anyone who knows how to fix this?

My Datastore in case it could be something that does so it doesn't work

local datastore = game:GetService("DataStoreService"):GetDataStore("GameStore35") 

game.Players.PlayerAdded:connect(function(player)
    local leaderstats = Instance.new("IntValue")
    leaderstats.Name = "leaderstats"
    leaderstats.Parent = player

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

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

    local Rebirths = Instance.new("IntValue") 
    Rebirths.Name = "Rebirths" 
    Rebirths.Parent = leaderstats
    Rebirths.Value = 1

    local key = "user-" .. player.userId

    local storeditems = datastore:GetAsync(key)
    if storeditems then
        Coins.Value = storeditems[1] 
        Eggs.Value = storeditems[2] 
        Rebirths.Value = storeditems[3]
    else
        local items = {Coins.Value, Eggs.Value, Rebirths.Value} 
        datastore:SetAsync(key, items)
    end
end)

game.Players.PlayerRemoving:connect(function(player)
    local items = {player.leaderstats.Coins.Value, player.leaderstats.Eggs.Value, player.leaderstats.Rebirths.Value} 
    local key = "user-" .. player.userId

    datastore:SetAsync(key, items)
end)
