The classic slider is exactly the design for posts I wanted but is very frustrating. I spent so much time trouble shooting.
I added a simple classic slider and set Slides to show 4 (desktop) 2 (tablet) 1 (mobile).
On firefox and Edge, it shows one slide only on desktop (stretched from one end to the other). On Chrome it shows 4 slides correct;y. On my phone it shows two slides - instead of 1 (squashed). No matter what i try - this doesn't work.
