4. doesn’t automatically stop downloading new episodes even if you haven’t listened in a while
Agreed! That is a major irritation. It’s because I haven't listened in a while — on that particular device — doesn't mean I have given up on the podcast!
Another issue is the icons used for the interface. Downloaded episodes have a down arrow, which looks like an action waiting to happen — that you have to tap it to download the episode.
Then, there’s the ellipsis, which is used differently from Apple OS conventions…. It doesn't mean that it will being up a aet of options, but that the episode hasn't been downloaded. Over in Books, an item in the cloud shows one — OK, that refers to iCloud Drive, but an ellipsis doesn't convey downloadable.
Finally, one pulls down on the Library listing, and it downloads podcasts, even shows which ones have been updates. However, it turns out that many haven't been downloaded at all, yet they now show up in the podcast list. Many a time, I’ve gone for a walk after downloading episodes — or, even started listening to one — only to discover that the podcast is still in Apple's cloud and not on my disconnected device!
This is basic functionality, basic Human Interface Guidelines, and clearly doesn't live up to Steve Jobs's mantra, “It's that simple!”
Alas, Apple, it's not. It's an utter mess!
