That was it. Secondary USB-lighting cable must supply power to the Apple AV Adapter. I had the same problem on my iPhone XS and daughters iPhone 7 and could not get the Apple AV adapter to work with any of the suggestions above with the exception to this last one. I plugged in the secondary USB-lighting cable to a standard wall adapter and life is good. No need to connect the USB cable to the TV. My only guess is that previously the AV adapter was able to grab power from the phone directly over the primary lighting connector, but not any more on IOS 12

I have the same problems while using a Lightening>HDMI cable clone. Are you using the Apple HDMI adapter? Does it work? I was thinking of getting one to avoid the 3rd party software upgrade issues I can't resolve. I try to turn on mirroring but only see an Apple TV option I can't delete. I can't find any documentation to cover this new ios "feature" and no help from YouTube coaches.

so yes this worked IPhone 7 Plus running iOS 12.2 it wasn’t working an hour ago.

I came to this thread. I changed my display view like suggested and it now works.

Note: it doesn’t matter if it’s on zoomed or standard. Just change it—and remember to hit the word SET on the top right corner after making the switch.

CHECK your adapter now.

It should work.

And you can even switch back to standard or zoomed again and it will still work.

Somehow it just requires you to make that one change and then you can change it back.
