Why do TextLabel not refresh when you change the text?

Oftentimes I do a script like this.

while true do
TextLabel.Text = "bro"
wait(3)
TextLabel.Text = "can u chill?"
wait(3)
TextLabel.Text = "u cant see this cuz the guis not updating hahah ha ha"
end

As the 5th line says, scripts like this doesn't update the GUI, unless you reset, which will make the GUI updates to the latest text. However, the TextLabel will stay with that said text until you reset again.

The question is, how do I make it so that the text updates everytime I do TextLabel.Text = "text" without having to reset?

Bro you forgot to put wait() after the 6th line so the 6th line shows but then it changes instanly cause you forgot you put wait!

while true do
	TextLabel.Text = "bro"
	wait(3)
	TextLabel.Text = "can u chill?"
	wait(3)
	TextLabel.Text = "u cant see this cuz the guis not updating hahah ha ha"
	wait(3)
end

Do you have ResetOnSpawn enabled? If it is, which can be found in the ScreenGui's properties, turn it off.
