I did as you suggested, and get following
http://www.cropharm.com/croCS_top2.rcs - works fine
http://www.cropharm.com/croCS_bottom3.rcs -still does not work on apple device

I think the issue there is that these slides were created in v1.1. There may have been an issue that was already fixed in the latest version but impacted some projects saved in a specific build of 1.1. Try to re-create your other slider in v1.2 and that should fix the problem. If not, post a link to the file and we can look again.

Don't forget to also set your Slider ID. The bottom one was still set to cc-slideshow-8061c8db.

I will.
Thank you
