Global Surface Gui in FE mode?

Hello,

I've made a surface Gui that only works in Studio Solo mode, I've set the Gui to StarterGui and set its Adornee to the part. I've tried changing some text labels' text within the Gui in 2 ways. None of them work and I don't know what to do.

Before you continue: If you know what I can do, you do not need to give the script, you can tell me what I need to do.

Explanation how I made it "work"

A screen Gui in one client fires a remote event on ReplicatedStorage.
A script in the workspace is activated and fires AllClients

Ways I tried to do it but didn't work.

I've tried the following 2 ways.

--Way 1

	-- local script in surfaceGui is fired after the script in server fireAllClients
		
	game.ReplicatedStorage.UpdateGateInfo.OnClientEvent:Connect(function(plr,value)
		script.Parent.TextLabel.Text = value -- Value is a string
	end)

--Way 2

	-- Script in workspace is fired from the remotEvent which was fired from a ScreenGui

	local plrs = game.Players:GetPlayers()
	for i = 1,#plrs do´
		plrs[i].PlayerGui.SurfaceGui.TextLabel.Text = "Test"
	end
	

I don't know what else to do,

I don't know if this helps with the issue but a script I have in the SurfaceGui only works in Studio Solo as well. It doesn't do anything, it should get os.date but it doesn't do anything. PS: The os.date script is a script inside surface gui, as I was getting errors with Local scripts in Studio Solo.
