Thank you for contacting Rank Math and bringing your concern to our attention. We are sorry for any inconvenience this issue may have caused you.
To answer your question, yes, the PRO plan is different from the Content AI Starter Plan. You can purchase the Rank Math PRO plugin here: https://rankmath.com/pricing/

If the issue still persists, please follow these steps:

3 . Once you’ve disconnected your Rank Math account, you can connect it again in the same settings. In order to connect your correct account, click on Connect Now.
4 . Once you click on Connect Now, please ensure that you’ve selected the correct account and then click on OK, Activate Now.
5 . Once all the above steps are done you might need to refresh the credits again this time to start using Content AI.
Please head over to WordPress Dashboard → Rank Math → General Settings → Content AI and refresh the credits. Here’s a screenshot for reference:
