For Canadian users there is a simple fix that requires you to install an app from the play store called Quick Remote.
Once installed link your tv to the app and select the device you wish to control.
Lastly use command "hey Google let me talk to quick remote"
Quick remote will respond in a male voice and ask you what you wish to do.rest is sinple...
Anytime you want to command it say, hey goofle tell quick remote to....
Launch netflix (or other channel)
Turn tv off /on
This works like a charm for me.... The only thing i cant get it to do is launch specific shows on channels. For example if i say, hey google tell quick remote to launch Tje Expanse on Prime Video. It ackniwledges that its doing it, but doesnt do it. So if someone finds a fix for that, it would be awesome!
