An app can ask to browse the local network to find nearby equipment. Apple lets you allow or revoke that access, but the permission’s effect depends on the feature and the app.
Do not describe Local Network as a universal switch for all internet playback or every AirPlay action. Apple explicitly distinguishes direct app access from interactions through system services.
Read why the app is asking
Notice which action produced the prompt. A streaming app looking for a connected display may explain that purpose in its message. If the reason is unclear, ask the developer before approving unrelated access.
Check the genuine app identity first. Permission approval gives the selected app access for a capability; it does not prove that the publisher is the one you intended. Keep the software verification and permission decision as separate checks.
Use the targeted privacy setting
Apple’s documented route is Settings → Privacy & Security → Local Network, where listed apps can have access changed. Review the intended app only. Do not disable other privacy protections, a firewall or every network control in an attempt to make a receiver appear.
If access is denied, the app may lose its own direct discovery function. However, Apple says the app can still use the internet or interact through system services such as AirPlay. Therefore, a missing receiver needs a precise description of whether you used the player’s own casting control, system Screen Mirroring or another route.
Change one relevant setting, then repeat that same documented feature. Record whether the receiver list changes. Avoid combining permission changes with several network and account changes, because the result becomes hard to interpret.
Keep the conclusion limited to the observed feature
If the app still cannot find a supported receiver, check the developer’s actual iOS casting requirements and Apple’s matching AirPlay guidance. The receiver, sender software and app support all matter. A shared Wi-Fi name is only part of that arrangement.
Do not post private device names, full account screens or playlist tokens while asking about discovery. A useful report names the app, iOS version, receiver model and the exact control used. Ask the developer which discovery route that edition supports and confirm the service account’s permitted use separately.
Useful answers
Does denying Local Network always disable system AirPlay?
No. Apple distinguishes direct app access from system services, including AirPlay. Identify the exact feature being used.
Does this permission control ordinary internet access?
It concerns local-network access. Do not treat it as the general internet-permission switch for the app.
