Using the built-in Android screen sharing option from the Settings > Connected devices menu, I have two available devices listed to share with, a Google Chromecast (for video) and a Vizio sound bar (for audio only).
Twice in the last two days I was able to choose either device, connect, and cast successfully once to each device. After disconnecting those successful screen shares, I cannot successfully connect to the devices to cast again. The status shows "connecting" for up to a minute before returning a message saying the screen sharing has been disconnected from the device.
An update to version 20I was delivered & installed on my V30 this morning. After the update I had one successful screen share, and then right back to failures.
I can cast to the Chromecast from within an application, like YouTube and Twitch without issue.
Another device on my family plan, a Moto Z2 Play, can use the built-in Android screen share (labeled "Cast" but has the exact same interface, settings location, & functionality as the LG's "Screen Sharing" feature) without problem.
So I've tested several different methods to cast and screen share to different devices using different smart phones and the only method that fails constantly is the Screen Share feature of my LG V30. Please help.
