Pandora not showing thumbs up or down

It shows up for me. Maybe a router reboot is in order?

Hi! If Pandora isn't showing the thumbs up or thumbs down buttons, try updating the app, restarting your device, and checking whether you're listening in a mode that supports ratings. You can also log out and back in or reinstall the app. If the issue continues, let us know which device and Pandora app version you're using so the community can help troubleshoot further.

I also get the thumbs.  Haven’t used Pandora in years.  Just now tested it.  Don’t care for commercials so don’t care for it.

The paid version dosent have commercials

Not Pandora but my Amazon thumbs have gone missing on occasion.

Fixes, in order of effort. Force stop the app and restart. Reboot just the router. Power down all Sonos, reboot the router and controller then power the Sonos back up.
