Hello @yair1515 ,
Thanks for opening a support topic. The notice you’re encountering is normal if there’s an Analytics snippet placed on your site, which your Site Kit connected Google account doesn’t have access to. By reviewing your site I can see the snippet in source code.
In order to be able to view Analytics data for this site within Site Kit you can perform one of the following:
1. If known ask the owner of this referenced Analytics property to grant you access at Analytics level, analytics.google.com. You may be the owner of this snippet yourself if you have another Google account, which wasn’t used during Site Kit setup.
2. Determine the source of the existing snippet and replace it with your preferred Analytics property, before then connecting the Analytics module within Site Kit once more
3. Determine the source of the existing snippet and remove it. You can then try to connect the Analytics module within Site Kit once more.
Note that if you remove or replace the snippet as above the statics will no longer be tracked on that property, which another administrator may be using.
If you want to share your Site Health information privately via this form we may be able to assist with determining the source of the snippet. It may have been placed via theme configuration, theme insertion (header.php or footer.php), Tag Manager or a third party plugin.
Let me know if you have any questions on the above.
Thanks & Regards,
