I use Siri in the car for Eye's Free and often say "Play Podcast XYZ". Since Friday this is interpreted as "Play Pulled Cost XYZ". At first I thought this was an iOS8/Podcast App v2.2 issue, but today, using my wife's iOS 7.1.2 and App v2.1.2 it gives the same response. If you manually text edit the question, it leaves Siri unable to help you! I have tried US and UK English, but get the same response. Reading these threads it does seem as if Siri is having some issues, but I am interested to hear if others have this specific Podcast issue. Will also visit Apple store to seek advice.
