Some media URLs contain signatures or tokens that are valid only for a limited time. Saving that temporary URL is different from saving the account's normal playlist entry. Reopen the item through the supported app to obtain current authorised access.
Recognise temporary access
A long query string may contain an expiry or signature, but do not edit it manually. Its structure belongs to the service. Sharing the link can expose access information even if it will later expire.
Use the normal catalogue
Refresh or reopen the programme through the player instead of reusing a copied media request from an old session. A favourite should point to the supported catalogue item, not a temporary diagnostic URL.
Ask about persistent failures
If fresh requests also fail, report the operation and time to support. Do not assume that a new account purchase is needed because one saved URL expired. Account duration and individual access-token lifetime are different controls.
