I had a glass screen protector on my iPad Pro 10.5 but it cracked so I wanted to take the protector off and replace it with a new one. I used the tech armor suction cups to remove the glass protector but it wouldn't come off. I pressed fairly hard on the iPad display while doing so a few times. I then figured out that I could take the protector off with my finger nail on the corner of the screen. Could I have done any damage to the screen when I put pressure on it? The display was off.
