New iOS-Update doesn't display websites properly anymore!

Hey guys,

I have a problem with the responsiveness on my website and I don’t think that it’s coming from my end, as every browser displays the website seamlessly except for iPhones that run iOS 15.4 or later.
When opening the website on iOS 15.4 the browser (no matter which browser) doesn’t respect the positioning and applied width of my elements which really bothers me.

By accident, I discovered that it starts working again once you move your iphone portrait to landscape and back to portrait. I doubt that this is a breakpoint problem but I wanted to find out what you guys think about this issue and if you have already experienced it yourselves.

Feel free to try it yourselves and let me know if it works for you. Here is the link to the website: (3)
