Basically a dupe of this question, but that one's still unsolved, so I'll ask again:
I'm trying to set up GA4 (I am not using Google Tag Manager). According to this doc, the following two pieces of code should accomplish the same thing:
1)
gtag('event', 'testing', {'foo':'x'});
gtag('set', {'foo':'x'});
gtag('event', 'testing');
But only the first one works as expected. With the second one, the property "foo" is ignored - as if I never made the "set" call. So what's going on?
