Web viewer does not display a link correctly

when through mit app I try to open this page, it opens it incorrectly, the same link I tried via pc, and smartphone and manages to open correctly, what am i wrong with?

link: https://www.exagonplus.com/booking2/?id=112233445

Something in the html that is too difficult or advanced for the webviewer?
The site doesn’t display properly in Chrome on my device (HTC10) either (no images, no menu)?

Web Developer perhaps needs to do some more testing for mobile devices…?

According to Google’s Mobile Friendly Test, the webpage concerned is mobile friendly:

Perhaps earlier in the day, the site’s web server had an issue?
