No longer able to stream movies with iPhone Lightning cable to Apple TV.

Hello Agatsea,

Thanks for the info. Let's try to resolve the issue for one of the apps at this time by deleting the app using the steps listed here: Delete apps on your iPhone, iPad, and iPod touch that are also listed below.

"How to delete an app

1. Touch and hold the app.
2. Tap Remove App .
3. Tap Delete App, then tap Delete to confirm.

Keep in mind that some built-in Apple apps can't be deleted from your device, so you might not see the option to delete an app. Here’s a list of built-in Apple apps you can delete from your device. If you can't delete an app that's not made by Apple, disable parental controls, then try deleting the app again."

Once done, please download the app again by completing the steps listed here: Download apps and games on your iPhone or iPad that are also listed below.

1. "On your iPhone or iPad, open the App Store app.
2. Browse through the Today, Games, Apps, or Arcade tabs to find apps you like. Or tap the Search tab to look for something specific. If you find a game that says Arcade, subscribe to Apple Arcade to play the game.

3. Tap or click the price or Get button. If you see the Open button instead of a price or Get button, you already bought or downloaded that app."

After redownloading the app, please try to stream content from it using your cable again.

Hope this helps!

Thank you for the reply Agatsea!
