Thanks for reaching out @iammerica.
Based on the error you’re describing this appears on the man Site Kit dashboard, and is as a result of the current Google account which is connect to Site Kit not having access to the connected Universal Analytics (UA) account, as opposed to the GA4 account. Site Kit displays data based on the connected UA account at present, although this will change soon to display data from the connected GA4 property.
As you’re already an administrator as advised, this may be for the connected GA4 property only, or it’s possible that the Site Kit connected Google account changed, resulting in this permissions error.
To resolve this, you can either disconnect your Google account from Site Kit and connect once more, this time using the Google account which does have access to the Analytics property. The account may have changed if you connected another service (ie. AdSense) after connect Analytics, with Site Kit switching to the Google account used to connect AdSense.
Alternatively, you can disconnect the Google Analytics module and connect once more. When connecting, you’ll be able to choose from any of the Analytics accounts and properties which you have access to.
Let me know if you have any questions with the above. We also have a guide on the plugin website in relation to this.
