activate CK Slideshow for mobile

Hi everyone,
I don't know if I have to set something, but on my site, CK Slideshow doesn't work on mobile phones.
The site is www.stadiumpro.it
I installed the CK Slideshow 1.4.63 version on Joomla 3.9.6.

thank you

Hi
the slideshow works, but your template hides the container "sp-slider" under 991px ...this is something to check in your template or use another module position

Thanks for the quick reply.
But can I select different positions for mobile or desktop ??

you can not select different positions , you must use a position in your template that does not hide on mobile
or use another template ...

or have I uploaded images that are too large for the mobile?
is there a limit to the size of the images?

absolutely not ...
I'm trying to explain you that the slideshow is not in cause, and is working
1/ you have a slideshow loaded in a module position from the template => "sp-slider"
2/ on desktop "sp-slider" is visible
3/ on mobile (under 991px) "sp-slider" is hidden from the template . BUT the slideshow is still there and working, the only problem is that you don't see it

you can try to force this in your template with a
is it clear for you ?
