Hello,
Thank you for contacting Rank Math, and sorry for any inconvenience caused.
The couldn’t fetch error, is in most cases simply due to a bug in the Search Console.
Please follow this guide to fix the issue:

For the Site Analytics, as you have imported from Yoast, Analytics shows No data.
The tests work when you open the posts and then the JS for calculating the test runs. When the test runs and you hit the update button, the score is calculated and gets propagated to the list view and Analytics. Since you imported the keywords, the JS didn’t run and the score didn’t calculate. You will need to open the posts, let the tests run, make optimizations based on our recommendations, and save the posts and the score will get propagated to the list view and Analytics.
Unfortunately, there is no feasible way to automate this process.
However, please note that this does not affect the rankings as the SEO score is just an internal metric.
We recommend that you start with your most important posts, open them, make changes as per recommendations made by Google, and then hit the update button.
If you were to import any other plugin from another SEO plugin – you would need to follow the same procedure.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
