@downey Had the same nonsense with our national tax agency when I needed to give my wife permission to get my info. The process involves DigID, our national identification platform, which has a web interface and apps for Android and iOS.
The tax agency give you a link to follow, but that only works on mobile (because of course it does, even though there's no technical need for it), and then only in a handful of browsers (of which Samsung Internet isn't one). So I have to copy and paste that URL into Chrome, like a caveman, have it kick off the identification through the app, which redirects me to my default browser, still Samsung Internet, but now it's suddenly OK and the permission is granted.
Maddening. Several hurdles that have no real use.
