I followed this tutorial https://support.wix.com/en/article/how-to-use-wix-code-to-display-elements-in-mobile-only to display a button in mobile only.
If in the properties panel "Hidden on load" is selected the button doesn't appear neither in mobile nor in desktop.
If "Hidden on load" is deselected nothing happens neither in mobile nor in desktop.
I took a look to other post in the forum with similar issues but I didn't find a solution.
Can someone help me?
