Issue while purchasing subscription

Hi, I just purchased a basic plan, however, after going through the steps purchasing through paypal it resulted in a page that just says “expired”. I’m guessing because I had started the process of purchasing and had to walk away for a second, forgot I had it open in another tab, started the process with paypal and realized I’d already started it, so I closed the tab. Well, anyways the payment went through, it says I made a payment for $69 to FastSpring. However, I wasn’t logged into rankmath.com’s site at the time of the purchase but when I logged into rankmath with my google account it shows I don’t have any subscriptions. I used the same email as my google account when signing up, but i think something got messed up somehow.

EDIT: Ah just before I sent this I checked my email again and I have some emails confirming the transaction and it takes me to https://rankmathllc.onfastspring.com/ where i can login and manage the subscription. However, is there a way to sync this to my google account login for rankmath? It’s much more convenient to just use oAuth to sign in and manage so I don’t have to remember passwords for every dang site. If you need I can supply the transaction number or you should be able to look it up with the same email as what’s attached to this account here (well, assuming the CMS you’re using knows who’s sending this email… haha)

Thanks for the help in advance!
