Website does not load correctly in Instagram broswer

We are selling clothing and want to go live this week. Now we have run into a major issue.

Our website completely buggs out when opened via Instagram, our main social media channel for reaching our customer… (check: @creamdesignofficial and then link in bio. Compare to when opened in normal browswer).

Colors change, text is not readable because of it anymore or the website completely just does not load at all. It’s horrible.

We are using the divi theme plus woocommerce and have no idea as to why this is happening and what we can do about it. It works on the normal phone view and desktop view.

Any help is greatly appreciated. Let me know if you want me to provide further info.
