When I use the GA4 Measurement Protocol directly through HTTPS requests without Firebase or gtag.js, Google Analytics does not show any user-info such as screen resolution, location, language, etc., which I try to pass with user_properties or events. Maybe I'm using the wrong tags or the wrong place to pass these variables?
I've tried to use sr/screen_resolution, ul/location/country/geoid, language/lg, ...
How to pass these variables and in which format manually? Firebase and gtag collect them automatically, but since I do not use them (and do not advise to use them), I wonder how to do that in the right way.
I also tried to register these properties with custom definitions, but that did not help.
