Why can I open a menu on PC but not on Mobile?

I used an Activated event to trigger this function. It works on PC but on mobile the button just goes dark when I click it, but no menu pops up. I know that the If parameter for ContinueScreen doesn't mess with it, I tried removing it and testing on mobile but same result.

Script:

button.Activated:connect(function()
	if (not main:FindFirstChild("ContinueScreen")) or (main:FindFirstChild("ContinueScreen") and main.ContinueScreen.Visible == false)   then

			menu.Position = UDim2.new(0, 0,0.2, 0)

			Sound.Pitch = 1
			Sound:Play()
			if button.Title.Text == "Menu >" then 
				button.Title.Text = "Menu <"
				button.Title.DropShadow.Text = button.Title.Text
				char.Humanoid.WalkSpeed = 0
				menu:TweenPosition(UDim2.new(0, 0,0.2, 0),"Out",'Quad',.25,true)
			elseif button.Title.Text == "Menu <" then
				Sound.Pitch = 1
				Sound:Play()
				char.Humanoid.WalkSpeed = 16
				button.Title.Text = "Menu >"
				button.Title.DropShadow.Text = button.Title.Text
				menu:TweenPosition(UDim2.new(-0.1, 0,0.2, 0),"Out","Quad",.25,true)
			end
		end	

end)

I probably made a stupid mistake but if anyone is free to help I thank you in advance.

Here's code with my explanation, let me know if you run into any issues.

local MenuOpened = false -- I believe a variable might be good for this scenerio.

--[[
Consider using InputBegan, it's widely used and easy to figure out.

If you're wondering...

UserInputType is the type of input recieved (keyboard, mouse, touch).
UserInputState is the state of the input (begin, end, changed).
]]

button.InputBegan:Connect(function(InputObject)
	if InputObject.UserInputType == Enum.UserInputType.MouseButton1 or InputObject.UserInputType == Enum.UserInputType.Touch and InputObject.UserInputState == Enum.UserInputState.Begin then
		MenuOpened = not MenuOpened
		if not main:FindFirstChild("ContinueScreen") or (main:FindFirstChild("ContinueScreen") and main.ContinueScreen.Visible == false) then
			menu.Position = UDim2.new(0,0,0.2,0) -- Not sure why you put this here, this could interfere with the tween, I kept it anyway.
			if MenuOpened == true then
				Sound.Pitch = 1
				button.Title.Text = "Menu <"
				button.Title.DropShadow.Text = button.Title.Text
				char:FindFirstChildWhichIsA("Humanoid").WalkSpeed = 0
				pcall(menu.TweenPosition,menu,UDim2.new(0,0,0.2,0),Enum.EasingDirection.Out,Enum.EasingStyle.Quad,0.25,true)
			else
				Sound.Pitch = 1
				char:FindFirstChildWhichIsA("Humanoid").WalkSpeed = game:GetService("StarterPlayer").CharacterWalkSpeed
				button.Title.Text = "Menu >"
				button.Title.DropShadow.Text = button.Title.Text
				pcall(menu.TweenPosition,menu,UDim2.new(-0.1,0,0.2,0),Enum.EasingDirection.Out,Enum.EasingStyle.Quad,0.25,true)
			end
			pcall(Sound.Play,Sound)
			--[[
			'pcall' is good for preventing errors that are not necessary.
			I use it very often, and I encourage it.
			
			Here's a good example of it:
			
			local success,response = pcall(function() return "this is what response will be" end)
			print(success,reponse)
			Output:
			> true,"this is what response will be"
			]]
		end 
	end
end)

I just changed my original event which had MouseButton1Click into MouseButton1Down. For some reason it fixed everything, found it on some roblox dev forum or something. Thanks for trying to answer my question!
