Modules positions on mobile

[Kantyl]

Hello,

 

I'm configuring the modules positions on my PC and everything goes well.

 

But when I'm looking at my site on my mobile, some modules are there and some are not.

 

For example, on displayHome, I have the Facebook block and the CMS Customer Info Block. They appear side by side on my PC, but on my iPhone, I just get the Facebook block.

 

Is there some configuration somewhere related to the positions on the different kinds of devices ?

 

thanks.
