I use the DDG browser on iOS, and it has a feature that lets you ‘fireproof’ a website so that the cookies for that site are persistent, enabling you to stay logged in on only the sites you want, while vaporizing all the history and cookies from all other sites.

This is handy and works fine on most websites and leaves me logged in, but doesn’t work at vger.app

I have specific reasons for not wanting the PWA on some devices, and everything works fine on the browser in the app, just have to keep logging in.

I realize this software is designed to be a PWA, but for cases like mine, why doesn’t this cookie persistence work?
