A media address can contain a time-limited token or refer to a short-lived playback session. That link may expire even though the underlying account remains active. Use the player’s supported account or playlist route rather than treating a captured media request as a permanent bookmark.
Distinguish entry points from session URLs
An account endpoint helps the player obtain current media access. A link observed during playback may be generated only for that session. Saving the latter can bypass the normal refresh process and fail after its token or referenced media window expires.
Avoid public link-testing services
A copied media URL can grant temporary access and reveal account information. Do not paste it into unfamiliar players or diagnostic websites. Report that the supported player fails to obtain a fresh stream rather than exposing the captured URL.
Reopen through the normal interface
Stop the old session and select the item again in the supported player. If that works, the stale bookmark was not a reliable ongoing access method. If it fails too, record the time and visible error so support can investigate current account or source access.
