I have a problem in my Pandora app that has been going on since the last update or two to the app. If my screen is locked and an ad plays, the station will stop playing. Upon unlocking my phone, it displays an alert which reads something like, "Alert: we paused Pandora radio while the audio was muted." After clicking an okay button and hitting play, I'm good to go. This problem does not occur consistently and is only an annoyance. However, if anyone has encountered this problem before and has a solution, I would certainly appreciate hearing it.
I should add that I am running iOS 6.1.3 on an iPhone 4S. So perhaps this issue is related to something about my phone being not necessarily up-to-date? If so, I can tolerate this hiccup for the time being. As I said before, though, any input would be greatly appreciated.
