Hello, I think I have identified the problem. I dont understand why you do data saving in this way, will only work on single player game, but thats your bussiness I guess. The problem was you were getting a sync from player.UserId but you were saving data like player.UserId_portal. I fixed the code for you. I recommend you to not copy code from internet and write it all yourself, because I cant imagine how you could make this error in other way.

local dss = game:GetService("DataStoreService")
local sv = dss:GetDataStore("Save1")

game.Players.PlayerAdded:Connect(function(plr)
    for i,v in pairs(game.Workspace.Teleports:GetChildren()) do
        local tp = v.Bought

        local data
        local succ, err = pcall(function()
            data = sv:GetAsync(plr.UserId, v.Bought.Value)
        end)

        if succ then
            tp.Value = data
            print("Succ")
        end
    end
end)
for i,v in pairs(game.Workspace.Teleports:GetChildren()) do
    game.Players.PlayerRemoving:Connect(function(plr)
        local data = v.Bought.Value

        local succ,err = pcall(function()
            sv:SetAsync(plr.UserId, v.Bought.Value)
        end)

        if succ then
            print("Data Saved")
        else
            print("Error Data")
            warn(err)
        end
    end)
end

Here is the fixed code. I wish you good luck in future with scripting, and I hope this helped.
