After iPhone 16.3 update, when using Airplay w Roku, mirroring still works but it does not switch to streaming when playing videos. It continues to mirror, playing on iPhone screen and Roku screen with the wrong aspect ratio. How do I get it to stream the video full screen to Roku (w only controls on phone while playing video) like it did before update?
iPhone 11 Pro, iOS 16
Hi MarkalanT,
First it's a good idea to ensure your Roku device is compatible and has the appropriate software to support these functions. The page How to use AirPlay and HomeKit with your Roku® streaming device includes a list of devices and a correlating minimum software requirement.
Your iPhone appears to meet the minimum from that page with the information you provided.
That article also offers configuration steps as well as this specific section on AirPlay with videos:
"How do I use AirPlay to view videos, music, and photos on my TV?
Before you can use AirPlay with your Roku device, check that your Apple device and Roku device are on the same wireless network. Once they are, you can use the steps below to view content on your TV using AirPlay.
Once playback begins, you can pause, fast forward, and rewind from your iPhone, iPad, or Mac, or you can use your Roku remote. When you want to stop streaming with AirPlay, you can press Home on your Roku remote."
Regards.
