Podcast app using huge amounts of "hidden" data
I noticed that the second most data hungry app on my phone after my Photo library is the Podcast app, despite using the "Remove Played Downloads" setting enabled and religiously deleting any straggler episodes. Apparently this app is using 6.76 gigabytes of storage, despite the grand total of the stored podcasts I currently have on my phone being 413 megabytes. I'm just wondering if anyone knows what this mysterious >6 gigabyte chunk of data is, and how I can purge it.
