Lightning to HDMI adapter not working
I just purchased a brand new Apple lightning to HDMI adapter. I’m using an iPhone 11 Pro with iOS 14.0.1. But when I plug it in nothing happens. I’ve tried different HDMI cables and 2 different TVs. But it’s like my phone doesn’t even register that the adapter is connected. It charges it but does not display video or play sound on my TV through any app. I’ve got a week long hunting trip coming up where being able to play videos from my phone to the TV in my camper is the only source of entertainment I have so any help will be appreciated.
iPhone 11 Pro Max, iOS 14
