1. Click Admin.
2. Make sure you are in your GA4 property.
3. In the Property column, click GA4 Setup Assistant.
4. Next to "Setup Assistant", look for a green "Connected to" notice. This notice tells you which Universal Analytics property this GA4 property is connected to. If the green notice is missing, your GA4 property is not connected.
