On my side, I have added the following rule which apply on mobile an also when the width of the popup is larger than the page
.spb-popup-main-wrapper{ max-width: 100% ; }
This allow the popup to auto-resize on the page width.
I think this should be added in the default css of the popup - 🇮🇹Italy finex
I've created a library override on my theme redefining the JS and CSS using flexbox to improve the responsiveness (I'm using libraries-override to completely remove the module js/css because I've also refactored the js without jquery and fade it/out effects).
