Update on replay settings
Corrected issue I had with access to episode replay and/or manual deletion.
Here is what was needed ...
After playback, an episode appeared in the "downloaded episodes" page, allowing me to either listen to it again or manually delete it - only after I had deselected in the automatic cleanup settings "mark played." ("Mark played on deletion" was kept as selected. "Delete" in the "after playback" section was kept as deselected. "Delete downloaded episodes when you mark them as played manually" in the automatic cleanup section was kept as deselected. In "Player/Sleep Timer" setting, "Keep Episode" was kept as selected.)
I mention all of these settings, because after playback, both after completion using the sleep timer and without it, an episode was disappearing. I wanted to have the option of keeping it listed so I could either access it again or manually delete it. At this point, it seems that deselecting in the automatic cleanup setting a downloaded episode marked as played, corrected the problem.
It would seem that unless that setting is deselected, after playback, an episode is classified as played and it automatically disappears.
