Hello,
Thanks for contacting us, and sorry for any inconvenience that might have been caused due to that.
Our dev team released a Beta version of the plugin that improves the Analytics module and makes the data import process run much smoother.
Please try updating to the latest beta version of Rank Math by following this guide: https://rankmath.com/kb/version-control/#beta-updates
Once you’re in beta version of Rank Math, please head over to WordPress dashboard > Tools > Scheduled Actions > Pending.
or you can try visiting the following URL:
https://yourdomain.com/wp-admin/tools.php?page=action-scheduler&status=pending
Run the rank_math/analytics/data_fetch scheduled action and wait for the data fetch to complete.

After that, please allow Rank Math a while to fetch data from Google Analytics and you should be able to see the updated data on Rank Math Analytics dashboard.
Let us know how that goes. Looking forward to helping you.
Thank you.
Thank you for your reply. I updated my RankMath plugin to the beta version. Pressed run under Scheduled Actions, and it didn’t work.
Reconnected the account, deleted data, and forced to update manually. It went through the 180 newly added pending hooks, without results. In analytics, data rows remains 0, and size remains 80kb, just like it was before deleting the data. The storage days is also showing me 0 days, and trying to update that to any other number between 0 and 90 doesn’t change that. Screen capture added below.

Hello,
We updated the plugin to the latest version which includes improvements in the Analytics module and triggered the actions to run and fetch data.
We can already see some of the data getting populated:
