Why don't my gamepasses work until player quits & rejoins game?

Hello! I have my gamepasses set up where a player clicks on a sign and purchases the gamepass. When they purchase the gamepass, the "gear" they purchased does not appear in their inventory until they leave & come back.

Any suggestions?

Both scripts are in Workplace.

local Id = 5555555 -- gamepass ID
local VipPlayers = {"test"} -- VIP Player
local ToolName = {"test"} -- Tools in ServerStorage

local function FindPlayer(Plr)
    for Num, Pler in pairs(VipPlayers) do
        if Pler == Plr then
            return true
        end
    end
end

game.Players.PlayerAdded:connect(function(Player)
    if game:GetService("MarketplaceService"):UserOwnsGamePassAsync()(Player.UserId, Id) or FindPlayer(Player.Name) then 
        Player.CharacterAdded:Connect(function(character)
            for Num, Tool in pairs(ToolName) do
                if game:GetService("ServerStorage"):FindFirstChild(Tool) then
                    game:GetService("ServerStorage")[Tool]:Clone().Parent = Player.Backpack
                end
            end
        end)

        for Num, Tool in pairs(ToolName) do
            if Player.Backpack:FindFirstChild(Tool) == nil then
                if game:GetService("ServerStorage"):FindFirstChild(Tool) then
                    game:GetService("ServerStorage")[Tool]:Clone().Parent = Player.Backpack
                end
            end
        end
    end
end)

This script is in the sign the user clicks on

local CLICK_BLOCK = script.Parent
local gamePassId = 5555555 

local Click = Instance.new("ClickDetector",CLICK_BLOCK)

Click.MouseClick:connect(function(UserID)
    game:GetService("MarketplaceService"):PromptGamePassPurchase(UserID, gamePassId)
end)
