Question :

I have some Chromecast devices (a Google Chromecast, a Google Nest Hub, a Google Home Mini, etc.) that I want to stream to from my iPhone. But even though te Apple AirPlay streaming option shows up, the Google Chromecast option only shows up in some of my iPhone apps and not in the other ones : in my case I can stream to Google Chromecast devices from the Spotify and Netflix iOS-apps, and not from Disney+, AmazonPrime and ZiggoGo…

What is wrong ? How can I solve this ?

Answer :

Even though AirPlay is always available on iOS/iPadOS and Apple AirPlay devices are automatically detected by default, the Google Chromecast option is turned off by default.

Since you can stream to some Chromecast-able devices and not to others, you seem to have turned on the option to do so per app individually. Yes, you need to switch on the Chromecast-ing option for each individual iOS/iPadOS-app…

To do so, do this :

• make sure that your iPhone/iPad is connected to the the same WiFi network that the Chromecast-device(s) that you want to cast to is/are on
• open the Settings.app in iOS/iPadOS
• in the Settings page that opens, scroll down to Privacy (the blue icon with the white hand) and click on it
• in the Privacy page that opens, click on Local Network (the blue icon with the white globe outline)
• in the Local Network page that opens, scroll down to the app(s) that you need and set it’s slider to ON (slide to right will make the slider green and turn the option ON)
  • your apps are now able to discover the Chromecast devices that are on the same WiFi network
• now, turn on the app that you want to stream from and the Chromecast-icon should appear (note that in most cases the AirPlay-icon will immediately appear and the Chromecast-icon will be added with a slight delay)
• then start the video (or audio) you want to play and click on the Chromecast-icon to select the Chromecast-able device you want to stream to

…that’s it !

enjoy 😉
