Nope. I asked on Stack Exchange too and no one had anything there either. I’ve yet to find anyone able to provide a way to get sliders working properly in the editor since ACF v6.
I even got in touch with ACF support and at first they were quite responsive, but eventually they just told me that it was a Slick Slider problem (despite me telling them I had the same issue with a different slider library too) and then stopped responding.
I just make the slider non-functional in the admin area these days, with admin-only styles to make it look like the front end version.
If you find a solution please do come back and share it here! It might help other people too.
