Will the update about google analytics be taken into account in xenforo 2.3 version?

AH!

Measurement ID not Property ID.

In GA4: Admin -> Property Settings -> Data Collection and Modification -> Data Streams -> Add Stream -> Web

Then in the Web Stream Details it gives the Measurement ID.

Got it.
Pretty sure this is caused by a delay.... pretty sad but their new Analytics stuff really sucks. It's crap... it's delayed by a couple days so your results will look like that.
