Hello,
Thank you for contacting the support, and sorry for any inconvenience that might have been caused due to that.
It seems on your account you are still using a Free license. Are you perhaps using a different account for your PRO license? If so, please provide your invoice number here when you purchase the PRO version of our plugin so we can further help you with your issue.
With that said, please disconnect your Rank Math account and reconnect it using your paid account. Head over to Rank Math > Dashboard > Help to do that.
That should fix the update issue.
Let us know how it goes. We are looking forward to helping you.
