Game Pass promptPurchase not showing thumbnail?

Hi!

My Game Passes work and are possible to be bought, but when the 'are you sure' window pops up, no thumbnail is being shown. I have looked on the web for this problem, but no luck so far. I saw that it is/was a known bug, but I'm not sure whether it's already fixed or not.

The promptPurchase script:

local MarketplaceService = game:GetService("MarketplaceService")
local Players = game:GetService("Players")

local gamePassID = 4713616  -- Change this to your game pass ID

-- Function to prompt purchase of the game pass
local function promptPurchase()

    local player = Players.LocalPlayer
    local hasPass = false

    local success, message = pcall(function()
        hasPass = MarketplaceService:UserOwnsGamePassAsync(player.UserId, gamePassID)
    end)

    if not success then
        warn("Error while checking if player has pass: " .. tostring(message))
        return
    end

    if hasPass == true then
        -- Player already owns the game pass; tell them somehow
    else
        -- Player does NOT own the game pass; prompt them to purchase
        MarketplaceService:PromptGamePassPurchase(player, gamePassID)
    end
end

script.Parent.MouseButton1Click:connect(function()
    local player = Players.LocalPlayer
    game:GetService("MarketplaceService"):PromptGamePassPurchase(player, gamePassID)
end)

Thanks!
