@vdriver My Thumbs Up playlist is only available when upgrading to Pandora Premium.
After checking the Pandora account associated with your community profile, it doesn't show any history of being upgraded.
If you paid for a Pandora Premium subscription in the past and had access to your My Thumbs Up playlist, it was likely done so on an account registered under a different email address.
This being said, I have created a ticket with our support team for you.
They will be contacting you privately via email to help look into this further, so please keep an eye out for their message.
Thanks for your patience in the meantime!
