I am working on a website right know, but I have a weird issue with the view on mobile devices. When I resize the window on a desktop browser the elements and fonts are changing with the viewport how they should. When I open the website on a mobile device all fonts and elements (e.g. the burger menu) are way to small. It looks like it is a scaling issue or something similar. I have the meta viewport tag in the head so that is not the issue.
I couldn't find any similar questions here or on any other forum. I hope somebody can help. I have attached some screenshots, but if necessary I can provide the URL. Thank you in advance.
