Symptoms
- No cast icon appears anywhere in the app
- Icon was there before and disappeared after an app update
- Icon appears in some parts of the app but not others
- Casting works from a different app on the same phone
Likely causes
- CommonPhone and TV/streaming device not on the same Wi-Fi networkThe cast icon often only appears once a compatible device is detected on the local network.
- CommonApp version doesn't support casting on that specific screen or content typeSome apps only allow casting for certain content, not live previews or menus.
- PossibleLocal network discovery permission not granted to the appNewer phone operating systems require explicit permission for apps to discover local devices.
- PossibleOutdated app versionAn old app version may lack current casting support.
- Less commonNo compatible casting device currently on the networkIf no Chromecast, AirPlay-compatible TV, or similar device is present, no icon will show.
What to do
- Confirm your phone is on the same Wi-Fi network as your TV or streaming device.
- Check the phone's app permissions and make sure local network access is granted for that app.
- Update the app to the latest version from the app store.
- Restart the phone and the streaming/casting device.
- Try casting from a different screen within the app (e.g., a show's playback screen instead of the home screen).
- Confirm your TV or streaming device actually supports casting or AirPlay.
- Reinstall the app if the icon still doesn't appear after these steps.
When to call a pro
