Redirect Mobile issue

Hi, I need to redirect 2 forms to a thank you page. I used your code:

<script>
document.addEventListener( 'wpcf7mailsent', function( event ) {
    location = 'https://example.com/';
}, false );
</script>

and it works perfectly on desktop but on mobile, when someone clicks on the contact us page link, it automatically redirects them to the thank you page. This is the same for both forms.

I also tried 2 plugins for contact form 7 that promise to do the same thing and the same thing happens. On mobile devices redirects them automatically. How can I fix this? I need ASAP ??

The page I need help with: [log in to see the link]
