user's properties can't update

[AruSeito]

Bug Description

Bug description

When using posthog-react-native, I repeatedly use the following code:

posthog.capture("set_user_properties", {
        $set: {
          utm_source: utm_source,
        },
        $set_once: {
          $initial_utm_source: utm_source,
        },
      });

However, the user profile is not being updated, even though I can clearly see two different utm_source values in the user panel.

How to reproduce

1.Set utm_source = test_source1 and use the above method. At this point, in the event panel of the user profile, the set_user_properties event is correctly logged, and both initial_utm_source and latest_utm_source are displayed correctly. The user properties appears to be updated as expected.
2.Change utm_source = test_source2 and repeat the steps from the first scenario. While the event panel still shows the correct values, but the latest_utm_source in the user properties do not get updated.

Hey @AruSeito, this does looks like a bug when setting $initial_utm_source (with dollar sign) inside of $set_once that would need to be looked into.

In the mean time though, you can change your code to:

posthog.capture("set_user_properties", {
    $set: {
        utm_source: utm_source,
    }
});

And PostHog will generate an initial value and save it to the person. utm_source is a campaign property and will get it's initial value set automatically.

CORRECTION: this doesn't seem to be working either. 👀
