after the wordpress update I can't view the page on mobile phones anymore

Dear support team,
after I updated to the new wordpress version I can’t watch the Homepage on mobile phones anymore.
It works perfectly in the preview version on my desktop or laptop, but on the actual phone it looks like the screenshot I attached.

this is the page url: http://breuer-photos.offsite-pr.com/

thanks in advance

Hello there,

I hope you are doing well today.

You need to disable the Jetpack mobile theme. Please go to Jetpack > Settings > Writing tab and scroll down to the Theme Enhancements, from here you can simply disable the mobile theme.

Best Regards,
Support
