Casting to my Roku stopped working on my Pixel 3a+ after the latest Android 11 update. The Pixel 3a+ now does not see the Roku device. But it continues to work on an older Android 7 phone. Also, the Roku remote app from the Google Play store no longer sees the Roku device on my Pixel 3a+ but it continues to work on the Android 7 phone. Apparently Android 11 has added security measures that block the functionality that these apps use to cast to the TV.
Any word from Google about this issue? Surely they aren’t doing anything evil here, right?
