Hi @dandr69,
Thanks for getting in touch. When you mention V4 I assume you’re referring to Google Analytics 4 (GA4)? If so, then it’s normal that Site Kit will connect your site with both a Universal Type Analytics property (UA) and also a Google Analytics4 (GA4) property. We have more information on this on the plugin website below:
https://sitekit.withgoogle.com/documentation/using-site-kit/ga4/
Having both a UA and a GA4 snippet doesn’t impact reporting for each, with both properties working independently of each other. With regards the differences in metrics, if you’re comparing the Site Kit dashboards “All users” metric (which comes from your UA property’s “Total Users” metric from?analytics.google.com) it’s normal that this may not match the GA4 data for the “Users” metric, from?analytics.google.com. The “Users” metric which is highlighted here refers to?“Active Users”, which can differ from the “Total Users” metric, depending on how frequently your users return to your website. To summarize, GA4 highlights your “Active Users” whereas UA highlights the “Total Users“.

Let me know if you have any questions with the above.
