sharing buttons don't work at smartphone


I’m using AddToAny Share Buttons plugin. It´s working well at computer, but in smartphones I can´t click at the buttons. I asked it to the plugin support page, and they said me:
“On, the theme’s aside/sidebar element is [invisibly] overlapping most of the post, preventing anything beneath it from being clicked.
Always troubleshoot by temporarily switching themes and deactivating other plugins to find a root cause. In this case, one of the stylesheets in the “Newspaper X” theme is the cause. Let the theme’s author know about the issue so they can hopefully address it.”
What can I do to solve it?

Hey there,
I hope you’re doing well today

Kindly send me the URL to your website with the plugin activated so I may look into a viable solution for you.

Best Regards,

You can see the buttons at this page:

Thank you!

Hey there

I hope you are well today and thank you for your question.

You can try achieving this by adding the following CSS code in the Custom CSS option of your theme on the below path.

Admin Area -> Appearance -> Customize -> Additional CSS

/*fix share button on mobile */
.addtoany_share_save_container.addtoany_content_top {
    position: relative !important;
    z-index: 99999 !important;

Best Regards,

It worked! Thank you very much!
