Why can't I view media off-line?

If you plan on being offline and use the app, it is always a good idea to start by manually checking for updates/Syncing in Settings before hand. Even if you have the toggle set to automatically Sync/Check for Updates, we recommend manually pressing the button to ensure every available item is downloaded.   

Some pieces of media may be tagged as only available on line, there will be a small orange WiFi icon in the corner of the thumbnail that tells you it is only available when connected to a network.

Once you reconnect to a network, these pieces will again be available.
