Hi Juan,
Thanks for writing in!
I’ve checked your site and the widget is added in the sidebar that is appearing below the main content area. It could be possible to move it to the top on mobiles only with custom development, but this would be outside the scope of support we can offer. You may wish to consult a developer to assist you with this. X is quite extensible with child themes, so there are plenty of possibilities.
Thanks for understanding. Take care!
