Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
That is something all the SEO plugins need to have. The score is calculated with some Javascript functions, which runs when you load the edit screen of that post. Since you have migrated and haven’t entered and saved none of those posts, your score is not calculated nor saved.
Once you do, you will be able to see the score there. I know it might not be the most comfortable thing and we are trying to find solutions for that, but right now it is the only way to get the score.
Looking forward to helping you. Thank you.
