Hello
Thank you for contacting the support and sorry for any inconvenience that might have been caused due to that.
You have marked this ticket as resolved. However, if your issue hasn’t been resolved, could you please follow the below steps?
Step 1: Disconnect your account from WordPress Dashboard > Rank Math > Dashboard > Help
Step 2: Reconnect from the same page using the same account you used to make a purchase. Here is a KB to help you along the way as well: https://rankmath.com/kb/how-to-upgrade-to-rank-math-pro/
That should fix the issue.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
