I have ensured that I deleted any downloaded episodes. I have unsubscribed from the podcast from within the app. I have confirmed that I am not subscribed via the web portal.
Podcast still shows up under "my podcasts" tab in the app. I can even resubscribe and unsubscribed (which I've done) from within the "my podcasts" tab.
Any options to purge the podcast "ghost" from my phone?
