I put the first of the 2 pack of screen protectors for my Apple Watch Ultra on and within a few weeks I had multiple cracks in the protector. I never hit the watch against anything. There were no impact points visible on the screen protector.It just cracked. So I left it on for a while until I decided to pull it off and put the 2nd from the 2 pack on the watch. Same thing happened on this one as well. I am looking at the protector now and there are probably 5 cracks.
They all appear to start around the spot nearest the crown and radiate out from there. Not only straight across the watch to the left but also to the upper left corner and some cracks in between those two main cracks.
I am wondering if there is something going on with the Apple Watch Ultra where there is a little flex in the factory screen that Spigen did not take into account?????
