Never tried that but I don’t think it fits. The size of different iPad generations are not the same, they all have specific design. So the screen protector or the case of one iPad model should not be suitable for another.
Does this site only deal with Android tablets? What about iPads? I don’t seem to find anything about iPad or iOS. I have an Samsung Galaxy Tab 1 but am thinking about changing to iPad Pro. Can’t find anything, maybe I made a mistake? I suppose to find any of these iPad models.
