Hi, I figured this one out.
For anyone out there with same issue, it’s hard to find but order of these slides is set in the Gallery, which as far as I can tell, is only accessible when setting the Feature Image. There in popup, you’ll see Gallery tab, and the order of slides can be set by entering numerical order next to each slide, then press Save.
If you are using a proper WordPress gallery in body of your Portfolio Post, it may be different, i.e. you can edit via gallery, but I’m just inserting images into body of the post and it was a mystery until I just happened to be changing Feature Image and saw that tab.
For Rime update, perhaps you can add drag and drop for image order down below in Portfolio Options? That would make it much easier/intuitive.
