Hi @Aidan thanks for posting to community.
I checked the account that is associated with your community profile and it sounds like you have more than one Pandora account.
This account has not been upgraded in the past and digging a little deeper it looks like the last station created was in 2017.
Is it possible you created another account with a different email address and upgraded?
If you're having trouble finding your account, let me know and I can have our user support team contact you for further help. 👍
