ZAGGIS-Fusion Curve AM B-Samsung-Hurley-CFS-FG

I'm looking for a zagg shield for samsung galaxy s23 ultra. what is this samsung s23+? samsung s23+ is not the same as samsung galaxy s23 ultra…?

What cases will work with it? Is it case friendly with all cases?

Why does the Zagg screen protector for S23+ have so many bad reviews?? They're normally great.

Should this fit to the bottom of my Samsung Galaxy S23 Ultra? Mine has a gap and when I swipe up from bottom, it is very noticeable.
