Not sure what the issue is.  I have posted the solution that worked for me on this thread.  It comes down to removing the Pandora app from Sonos app and adding it again.  I have not experienced any problems in the past three weeks.  best of luck ... View more

Hi.  In Sonos app tap settings.  Tap services and voice. Tap Pandora then tap reauthorize.    in order to avoid doing this every day you are better off by removing the Pandora service in the Sonos app then adding the service again.  best of luck ... View more

In Sonos app.  Go to settings.  Then services and voice.  Select Pandora then reauthorize.  Best option to avoid doing this is to remove the Pandora service from Sonos app then add it back up.  This solved the problem for me.  ... View more

Hi. This is working now I removed Pandora service from Sonos app and added it again. I have not needed to reauthorize Pandora in two days. Seems to work fine now. 😁😁😁😁😁 Sent from my iPhone ... View more

Did you have to add the stations back in by doing that? After adding Pandora back to sonos? Just wonder if the stations settings will be lost. Sent from my iPhone ... View more

As far as I know nothing. I am in the same boat as you. I have the Pandora App on my iPhone and I can play music on it without the reauthorization issue creeping up. The other issue is I have spoken three times with Sonos tech support and they are pointing the finger at Pandora. I have given up on this. I also have to reauthorize several times during the day. I read a post in the Sonos forum that with free Pandora there is Four hour timeout feature? Twenty four hour with the paid Pandora. This is quite annoying. Best of luck Sent from my iPhone ...

Agree. Only way around it is reauthorize every day. Sometimes even twice a day. Bummer. Funny thing is if you download the Pandora app. It’s not an issue. Only occurs with the Sonos app ☹️☹️☹️ Sent from my iPhone ... View more

Just to clarify.  I did not cast the app to the Sonos speakers.  I played music on my phone.   ... View more

Update.  I downloaded the Pandora app from the App Store and was able to play one of my stations without any issues.  Tried the Sonos app and got the message unable to play Pandora access is denied.  ... View more

The solution is to keep re-authorizing Pandora through the Sonos app. That is what I do every day. It is annoying for sure. Best of luck. Sent from my iPhone ... View more

Tanner...this is a more extensive reply.  Typically I use the SONOS app from my iphone 12.  I also have the SONOS app running on a PC with the latest version of the Windows operating system (64 bit).  I rarely use the SONOS app in windows and rely primarily on the app on my iphone. As of 7:01 PM this evening I tried to use the SONOS app on my cell phone and got the same message "Unable  to play Pandora - access is denied".  I had the same message this morning but once I reauthorized it I was able to play music all day on SONOS.  I read something on another post in the SONOS user forum about free Pandora having a 4 hour timeout feature?  Not sure if this has anything to do with it. Ill have to reauthorize it again tomorrow morning.   Thanks!           ... View more
