Update:
I’ve added a new slide to the slideshow (session 6), and I was hoping that it would show up in the slider, that only the last slide would be “missing,” but I was surprised even the 6th slide did not appear. As suggested, I changed the posting date/time of the slides so that when the user clicks on “next,” it will display the items sequentially from the first to the last slide.
I’m currently at a loss on how to proceed…
