Hi @TabithaBB! Thanks for posting to community.
If you are receiving the message, "Your Pandora Account is currently playing on another device," or "Someone else is listening," then more than one device is streaming from your account at the same time.
While your Pandora account can be logged into as many devices as you like, they can't be playing at the same time. Regardless of your subscription level, the revenue from one Pandora account only covers the cost of one stream from one device.
Additionally, while you can group your Sonos speakers to allow for a single Pandora account to be heard in multiple locations, only one stream (a single station, playlist, etc.) can play across the grouped speakers at the same time.
I checked the Pandora account associated with your community profile and I do see that 2 devices are attempting to play from this account at the same time. One from the Sonos and one from the Pandora desktop app. Looks like one device is playing 'Spa Chill Radio' while the other is playing 'Radiohead Radio'. If you were switching devices, be sure to press pause on one before pushing play on the other. From time to time the message can be tripped on accident when switching devices, and you can disregard the message.
If you believe this is an unauthorized user, then we can take some steps to help protect your account. This will require resetting your password and signing you out of all devices. It's more effective than simply changing your password.
Let me know.
