Rotating from lanscape to portrait – slideshow not responding

Something in my css or code is preventing the full screen responsiveness on mobile.

I checked the demo on my iPhone because the client said it’s not bouncing back into place when you turn the phone from landscape to portrait.

The demo works but my theme doesn’t. https://www.responsivejqueryslider.com/magicwordpress/bulletsFullScreen.html
