I don't have any ios devices, but I have multiple computers running windows 10, windows 11, and linux, and a oneplus 9. I have tried clearing cookies, removing all browser extensions and have tried on multiple browsers on each device and the app for the devices that have an app. It also happens on their party apps, so I'm confident the issue is not on my side. What changes did pandora make in the last two or so weeks? Also what fixes seemed to work for the people with the issues more than a year ago? I have not been able to predict or cause the issue. I work in IT and know how to diagnose issues. It is not on my side.
Since you mentioned this mostly occurring with your windows computer I've moved your message over to our Desktop Board and created a new thread.
It seems like you've tried a few troubleshooting steps already. Unfortunately, I have nothing more to recommend at this time. However, I've gone ahead and passed this along to our engineering team for further review and investigation.
