We have three Roku TV (2 TCL and 1 Insignia). Lately, the Insignia TV will turn on by itself when I open up the app on my phone (Android) to control the other TVs. This TV is in the guest bedroom so when we had guests over for Thanksgiving it startled them at night when I opened the app to activate Private Listening in our Master Bedroom TV. I have reset the TV; Fast Start is "disabled." Anyone else experience this or has some troubleshooting tips?
