Hello,
Thank you for contacting Rank Math support, and sorry for any inconvenience that might have been caused due to that.

Can you please search and forward a receipt from FastSpring.com so we can locate your account and confirm the purchase?
As for your issue, head over to your WordPress Dashboard > Rank Math > Dashboard > Help and on this page, you should be able to connect your account:

Let us know how that goes. Looking forward to helping you.
Hello,
I checked, my site is well connected, but my AI credits do not appear in my product pages. Attached are references and proof of purchase of Rank Maths SEO PRO and 50 credits.
Cordially.

Hello,
Thank you for contacting the support and sorry for any inconvenience that might have been caused due to that.
It seems like you purchased the plugin and Content AI credits with different email addresses than the one you’ve used to post this ticket.
Please have a look at the email addresses with the labels in the sensitive data section of this ticket.
This is the reason why you’re unable to access the PRO subscription as well as the credits on this account.
Would you want us to merge the accounts for you? If yes, please tell us your preferred email address.
Looking forward to helping you.
Thank you.
Hello, thank you for your quick feedback.
Yes, I want you to merge the accounts with my preferred email address d***********@n****** or if not possible with g**************@n******
Thanks for your patience and support.
Cordially.

Hello,
We have merged your accounts as requested.
Please check on your end if everything is working as expected.
Please go through this video tutorial that shows you how to get started with your PRO license:
Steps to be followed:
1. Ensure that you are logged in to your paid account
https://rankmath.com/my-account/edit-account/

2. Disconnect and reconnect your account from inside WordPress:

WordPress Dashboard > Rank Math > Dashboard > Help and click the connect/disconnect and then the connect button.
You will be taken to RankMath.com again where you can connect your account to activate your license.
You do not need to remove the free version of the plugin. Everything will be ported over to the PRO version.
Hope that helps.
Thank you.
