Is anybody using the new Google GA4 Analytics which they launched in Oct?

I started out using Google Analytics because I realised I shouldn’t rely completely on the Wordpress plugins that I was using on my website. Google also lets me track the traffic on my Patreon page.

I set all that up last year but then just discovered recently that Google has introduced a new Analytics ID tag. Is anybody else using it? I’m just wondering whether it’s worth taking the time to upgrade at this point.
