Keep storage state and access state separate
The publisher describes offline caching in its iOS and Android apps. It separately qualifies playback by the validity of the ticket or subscription. If a concert that previously worked no longer opens after access ended, that documented distinction should be checked before treating the file as corrupt or repeatedly downloading the same item.
For an illustrative trip note, record the concert title, the device on which it was cached and the date you intend to watch. Then inspect the account’s current access information. Check the dates in the account itself rather than assume that the presence of a saved item extends access.
Choose the local quality deliberately
The same help distinguishes HD and SD cache options, with different storage and transfer requirements. It also describes an additional audio-quality choice on iOS. Read the options in the current app on the intended device rather than assume every platform or release has exactly the same controls.
If storage is limited, compare the displayed size and chosen quality for the intended concert before starting another transfer. Keep a completed entry separate from one still in progress. Reopening the saved item before departure is a useful user check, particularly if subtitles, audio or another feature matters to the viewing session. Use the same device and account that will be available during travel.
Do not confuse caching with making an independent recording
The publisher’s recording FAQ states that recording concerts is not permitted, and the offline help describes its own controlled playback function. Use the supported cache rather than interpret a saved entry as an exported file that can be copied to another player. A download-like operation does not erase the access conditions attached to it.
For a remaining failure, retain the concert address, device, app version, completion state and access status for official support. Distinguish an expired entitlement from an incomplete transfer or a player error. If the title itself has disappeared from the current catalogue, identify that as a separate availability question.
Questions about this guide
Does a visible cached concert prove access is still valid?
No. The publisher says the copy can remain stored after the access period ends while playback is unavailable.
