Screen Mirroring
I used to be able to swipe up and choose screen mirroring to show my iPhone 8 screen on my LG TV, model OLED65C9AUA. The TV no longer shows when I select screen mirroring. This issue may have coincided with an update to iOS 14.1. However, I have another iPhone 8 plus that is running iOS 11.4.1 that I used to be able to screen mirror on the TV and it no longer works either. Did Apple do something or was it LG?
iPhone 8, iOS 14
