Hello,
Thanks for contacting us, and sorry for any inconvenience that might have been caused due to that.
Please make sure you’ve connected to the correct account.
If so, then I would like to request you to re-connect your Google account with Rank Math by following the steps I’ve mentioned below, without skipping them.
#1 ~ Remove Rank Math’s access from Google
Please remove RankMath’s app from your Google apps permissions:
https://myaccount.google.com/permissions
#2 ~ Re-connect to regenerate auth token from Google
After that, reconnect the Google account again, to regenerate the auth token from Google, by going to WordPress Dashboard > Rank Math > General Settings > Analytics and configure the Search Console and Analytics settings again:
#3 ~ Grant all necessary permissions
Kindly check all necessary checkboxes to allow Rank Math to access some of the Google Services. Please check my screenshot below for reference:
#4 ~ Setup Analytics
Once the above process is done, please follow the URL below to setup Rank Math Analytics properly:
