I’m having the same trouble. I upgraded to the previous update & then today, to 2.2.17 & my new slideshows will not resize. I have a slideshow that I created in an early version and it’s perfect. I’ve tried everything to get this to fix & can’t get it to work, even deleting the entire slideshow, resizing all of my pictures & recreating the slide show. My website is here: https://www.solstructures.com/?page_id=25 (Additions = not resizing). Kitchens = original slideshow that worked. I use Chrome. Any suggestions?
