In the latest Podcasts app, Apple have finally included the ability to sync podcast playlists from Itunes directly into the Podcast app. That's the good news.
However the bad news is that it only works if you do not have Itunes Match switched on. If you have Itunes Match, the playlists still do not appear. Furthermore, if you switch off Itunes Match, you then have to manually delete the playlists from your device within Itunes, and then resync again, for the playlists to then appear. If you then switch Itunes match back on, the playlists disappear again.
At the moment, Itunes Match, and playlists within the podcast app, are mutually exclusive.
They also seem to have added into the podcasts app the ability to create playlists automatically with a few options, but I'm not sure whether it meets most people's requirements.
Finally, the upgrade to the latest podcast app made about 200 very old podcasts that I had listened to and deleted long ago, mysteriously and apparently randomly reappear in the app and I had to then go through and delete them manually.
