If you've not downloaded anything recently it can take 5 minutes or so for the first item to start downloading, once started subsequent downloads will start immediately.

If you are still having issues then there are a few things to check:

  • You haven't accidentally paused the download - tapping on the download icon will pause/resume the download.
  • You have enough space on your phone or iPad to save the show.
  • You aren't low on battery or in low power mode - plugging in to charge when you're low on battery will help.
  • That you are on a fast and stable WiFi connection - poor data connection will cause your download to pause.
