After months of wandering the LG Store on my TV, and a good bit of money on useless apps, I chose instead to use an AppleTV (ATV) connected to my AVR, and pass the video to my TV. Alternately (for HBO and Netflix streams, you could add a Google Chromecast, $40US or so) — Chromecast does not use Apple’s AirPlay, and the pic of your phone’s Airplay pulldown would never show Chromecast as an option...) You could open the HBONow app on your phone and and choose the casting option, within the app itself. The Airplay icon, and the Google cast icons are similar looking, I’ve attached them here. . .
