Distinguish starting from finishing
A download icon changing state means the process has begun; it does not by itself prove all preparation is complete. The provider gives a flight example in which the user returns to the app before going offline. Build that return into your departure checklist.
For a practical sequence, choose the episode while connected, allow the transfer time, reopen the NOW application and inspect Downloads. Only then decide the device is ready for disconnected viewing. Do not wait until the aircraft has left the gate to discover that the title was only queued or partly prepared.
Check the correct device and collection
The same help says downloads are stored on the device rather than in the account. A film prepared on a tablet should not be expected to appear as a local offline copy on a phone. A Watchlist entry is also different from a downloaded item.
Nominate the device that will be carried and verify the selected episode there. If travelling with someone else, agree which screen will be used rather than assuming either account sign-in contains the same files. Keep the episode title and number in a short note so the intended viewing is clear if the programme tile changes.
Avoid removing the prepared collection
NOW says signing out deletes downloads. If a completed copy is already ready for the journey, do not sign out merely to tidy the application without considering that consequence. Inspect the original state and the expiry information first.
If a title is absent after the flight preparation, record whether you returned to the app while connected, whether sign-out occurred and which device performed the download. These observations separate incomplete iOS preparation, deliberate removal and a wrong-device expectation. The cited page is for the Republic of Ireland service; this guide does not extend its travel or subscription conditions to the United Kingdom or another regional NOW product without checking the corresponding help.
Questions about this guide
Can I assume a background iOS transfer is fully ready?
No. NOW directs users to return to the app while connected to complete preparation.
Will signing out preserve the downloaded collection?
The checked help says signing out deletes downloads.
