Steps to reproduce the issue

1. Open Browser on iPhone navigate to https://davidjakob.com - I tried with Safari and Chrome double-checked with friend
2. As above but with iPad - that's the devices I had to test with

Expected result

2. Site opens with slideshow module (Gantry Template) with all necessary navigation

Actual result

Only the logo, hamburger button and cookie consent button show up. Body is black, menu doesn't do anything, cookie button doesn't do anything.

Additional comments

This seems to be limited to Apple, as I have had no other complaints. I don't know if it's just my site or if it affects other Joomla/Gantry websites. Be good if it could be confirmed one way or another
