A saved poster is not a downloaded film
My List records a title you want to revisit. A checkpoint records the episode you last completed. The backup text carries those choices between browsers; it does not carry video, audio or subtitles. No movie file is downloaded by the Save button.
Prepare offline viewing through the chosen service
Find the production first, open Watch now and choose an edition available where you will watch. If its service supports offline viewing, use the supported app and inspect that film or season’s download options. Eligibility can differ within the same catalogue.
Before travelling, check the app’s download area, storage requirements and expiry conditions. Account changes or removing the app can affect stored editions. Do not wait until the connection is gone to discover that only a trailer or a list entry was saved.
For your Flixer choices, use list backup and restore. For the video itself, follow the selected service’s supported offline workflow.
