Hello,
Thank you for contacting Rank Math support, and we are sorry for any inconvenience that might have been caused due to that.
Can you please confirm to us if you see the correct number of credits when you log in to your rankmath.com/my-account/websites?

If you’re seeing the correct number of credits here like in the image above, then this is an issue with syncing information between rankmath.com and your website. Disconnecting and then reconnecting your account should mostly resolve this
1 . Please verify that you’re running the latest versions of the Rank Math plugins according to the Rank Math changelog: https://rankmath.com/changelog
2. After that, you may try disconnecting and re-connecting Rank Math to see if that works for you. Please head over to your WordPress Dashboard > Rank Math > Dashboard > Help, and from there disconnect and reconnect your Rank Math account.

Once you’ve disconnected your Rank Math account, you can connect it again in the same settings. To connect your correct account, click on Connect Now.

3. Once done, please try to refresh the credits from WordPress Dashboard > Rank Math > General Settings > Content AI and see if that works for you. Here’s a screenshot for reference:

You should be seeing your correct Content AI credit and you can continue using the Content AI. If not, please let us know and we’ll be happy to investigate it further.
Hope this helps, and please do not hesitate to let us know if you need our assistance with anything else.
Thank you for choosing Rank Math.
