PWA screen dimensions problem on portrait

I am having a problem that I have trouble explaining. I am making a Blazor web assembly app. When I publish it and look it on on my android phone on chrome on portrait view, the size of the top bar and everything looks reeeally small. And when I install it as a PWA now everything looks the right size. On samsung internet looks correctly.

This is the meta tag I am using:

<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />

Do I need to add something?
