Thank you for your help. I think this might be related to the integration with Waze. I usually launch Pandora from Waze. After clearing the data and reinstalling Pandora it was working perfectly. Then I linked Pandora to Waze and started having odd behavior. Not the same, problem, but for example, when switching to Pandora from Waze, Pandora was a blank pink page with only the version number at the bottom. Restarting Pandora fixed, but I was able to reproduce the issue by launching Pandora from Waze then opening the Pandora app and switching back and forth a few times. I did not see the Modes button disappear, so that's a good thing. Again, thank you.
