Pop-up window not working on mobile phone

Dear Webflow community,

I am trying to add a pop-up window on my homepage. The html code was generated by Leadpages as follows:

<script src="https://embed.lpcontent.net/leadboxes/current/embed.js" async defer></script> <script>window.addEventListener('LPLeadboxesReady',function(){LPLeadboxes.addDelayedLeadbox('BSNRPqQyuN9P25sAJYQH7d',{delay:'5s',views:0,dontShowFor:'1d',domain:'saschaandtheboys047.lpages.co'});});</script> 

I copied that code in the Custom Code box (before body tag).

The pop-up window works fine on the computer version but not on mobile.

Can you help me with that?

Many thanks
