yea I am guessing that u calculate center of the screen or smth? cause if u start in fullscreen then the next button never comes on screen, but if u start not in fullscreen the next button doesnt come on screen, but u can press full screen and then see the next button (altho some of the speech is still cut off). U may also want to just use gameObject.setActive(false) or GetComponent<SpriteRenderer>().enabled = false (then the reverse when reappearing) rather than just trying to move it offscreen so u can use it later
