I was having the same problem with the lg plus iOS app until today. Even though the lg tv was connected to the WiFi network in settings, there is a sub setting for an additional network setting that needs to be turned on under advanced, for ipv6 to be on. After that it worked right away.
I found that setting and turns it on. Still not finding my phone. 🙁
