[Plextalk] Cannot update key episodes in podcast flist

Hi, That (or something like it) is the message i get when I try. I've somehow lost the facility to update podcasts or download all podcast in the feed, on my PlexTalk Pocket. I can transfer them from the PC and can tune in radio stations on it. When i delete a podcast, the folder also is gone. Should the Podcast Feed manager also be on the PTP? At the moment, it appears not to be. Empty podcast feeds are not picked up by the PTP. I must have deleted something I shouldn't have, I think, or how should I restore the podcast update functionality on the PTP? Thanks.
