Google assistant does not recognize me as premium account holder

Google Pixel 3 XL

Android 9

Spotify V 8.4.84.874 - Premium

I am trying to use google assistant with my new phone, but it will not recognize me as a premium account holder. For example, when I tell Google assistant to play a specific song, it says  "Choosing songs is only available to Spotify Premium Subscribers. But give this Spotify _____ station a listen.". I thought it might be an issue relating to the google account on my phone, so I compared the email used with both my phone and spotify account, and found that they were using different emails, so I contacted support and had the email connected to my spotify account changed, but this still did not fix this issue. I also was advised to uninstall spotify, restart my phone, reinstall spotify, and then sign in again, but this did not work either. Please help.
