I have this problem too and it drives me crazy.
Details:
- iPhone 7 256mb
- iOS 10.1.1
- Verizon unlimited data plan
Repro:
- When the phone is freshly rebooted, the podcasts app works properly. As soon as it refreshes and finds a new podcast it immediately starts downloading.
- After the phone has been on for a day, maybe less this is what happens:
0. Precondition - connect to WiFi to avoid any question about the mobile network
1. Open the app
2. Note that it shows 8 podcasts downloads pending
3. Tap on the downloads
4. Note that it shows 8 podcasts all in "preparing to download" state
5. Attempt to restart the download by tapping a podcast to pause and tapping it again to resume.
6. Note that it still shows that podcast stuck in the "preparing to download" state
7. Navigate to that Podcast in the "my podcasts" or "unplayed" section and hit play (shows cloud icon indicating it has not been downloaded)
8. Note that it starts playing the podcast right away -- the radio works and the podcast app can download the podcast if you choose to play it. Only queued podcasts are stuck.
9. Reboot phone
10. Open podcast app
11. Note that podcasts immediately start downloading and are done in only a few seconds.
There's clearly a bug in the podcasts app.
