I am able to stream to the device using the Plex App, but enabling casting to a Chromecast prior to starting a stream will cause the phone screen to turn on and off as if I’m pressing the power button repeatedly. The only way to fix this is to use voice commands with Google Assistant to killplex which must be done three times for Plex to actually stop running and the phone screen to stop spazzing out. Sporadically, I am able to cast to the Chromecast if I first start a stream on the device and then transfer the stream to the Chromecast. I believe this only works if the Chromecast is not currently running the Plex app.
Looks like it might be. I was trying to find notifications within the app to disable first, but was unsuccessful. Interesting that someone else is reporting a similar situation with a similar potential solution/source point for the bug.
