Hello,
Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.
Please make sure that you’ve connected the correct Google account and not connecting to Google Search Console via a domain property but rather a URL prefix and that you have verified the correct version of your website on the Google Search Console (HTTP or HTTPS, www or non-www).
After that, please try reconnecting your Google Account again from WordPress Dashboard > Rank Math > General Settings > Analytics, and don’t forget to check all the necessary permission.

If the settings are not getting saved properly, please try saving the settings for the Analytics with a different browser such as Google Chrome. If you’re already using Chrome, then you can try it in Incognito mode just to save the settings.
Let us know how that goes. Looking forward to helping you.
Thank you.
Hello!
