Separate internet access from local discovery
An iPhone may load websites while a casting application cannot find the television. Those observations are not contradictory: reaching an internet service and discovering another device at home are different tasks. Note whether the Cast icon is absent, the device list is empty or a listed receiver rejects playback. That description helps avoid treating every discovery issue as a failed service login.
Check the app’s own permission
Google’s Local Network guidance explains the permission used by Cast-enabled applications on supported iOS versions. Look at the relevant application’s permission rather than assuming that granting access to another app covers every player. A past refusal can be changed through device settings if you later choose to permit discovery. Make that choice for the application you intend to use; broad unrelated permission changes are unnecessary.
Keep the network and receiver identity clear
The manufacturer guidance also calls for the sender and compatible receiver to be on the same Wi-Fi network. Check the actual network names and receiver selected, especially where a household has several televisions or guest networks. A similarly named bedroom device is not necessarily the living-room receiver you expected. Reopen the Cast-enabled app and inspect its list after the deliberate permission or network correction.
Test suitability after discovery
A receiver appearing confirms a discovery result, not permission to play every programme through it. The app and content must support the intended casting route. If a device is visible but one title fails, report that separately from an empty list. Keep account details private and include the phone version, app name, receiver model and the stage at which the failure occurs.
Questions, answered
Does allowing one Cast app automatically approve every other app?
Check each application’s Local Network setting. Permission and compatibility are tied to the actual app and device arrangement, so test the player you intend to use rather than assuming another app’s result applies.
