Action button on mobile phones

Could you please help me? My website is If to look at it on mobile phone then Action button English is not displayed instead of if to look at it on PC or tablets.
Why so? How to fix it?


The button is hidden on small screens to preserve space. If you want to turn it you can add this to a custom CSS plugin:

@media only screen and (max-width: 767px) {
    .header-button {
       display: inline-block;

Vlad, hi!
Works properly, thank you and have a nice day!
