Problem deleting/removing partially downloaded podcasts from iPhone
I have an infuriating problem where podcasts that fail to download properly still show up in my podcast library and refuse to be deleted by any method (can't swipe to delete) but which also cannot be 're-downloaded' from iTunes because iTunes thinks I already have them! The 'broken' podcasts have that new grey 'download in progress' symbol/icon next to them in the library, but are 'stuck' in this state.
How this happens, as far as I can tell, is that when I am downloading podcasts directly to my iphone over wifi, quite frequently of late there is a problem with the download - like it 'hangs', or I get the "unable to download at this time" error message, or it's just taking too long to download despite no problems with my broadband speed - so what I normally do in that situation is just 'swipe to delete' from the download queue in iTunes (on my phone). But now, when I go to the library section of my iphone - there the podcast is, but in an 'interrupted' state (with the 'downloading' grey icon next to it) - and I cannot delete or remove it. Or re-download it via iTunes. Maddening!
I've looked for people experiencing similar problems and there seem to be a few - but because of how complicated it is to explain I'm not 100% sure if we're talking about the same thing! Seems like syncing to your computer makes no difference either as basically neither the iphone or the computer can "see" the partially downloaded file - they are not admitting that it is there, only iTunes seems to think it is still there so refuses to let you have another go at downloading it.
Ugh. Can anyone help or shed light?? :-(
