Hello,
Thank you for contacting Rank Math today.
We just checked your account and the subscription is already showing as active and you can download the PRO plugin files from there as well.
Could you please verify the same from your side?
Looking forward to hearing back from you.
Hello,
As the PRO subscription is already active, please download and install the Rank Math PRO plugin (if not already) by following this tutorial guide:
https://rankmath.com/kb/rank-math-pro-license-key/
Once done, please head over to your WordPress admin area > Rank Math > Dashboard > Help, disconnect and reconnect your Rank Math PRO account to connect the website with your PRO subscription.
Here are some screenshots for your reference:


Hope this helps.
Thank you.
