I've been using Trigger CMD in combination with Google Home for over a year now, and it just works great.
However, as of approx. two months ago, I keep getting signed out of Trigger CMD in my Google Home-app (Android). When trying to invoke Trigger CMD, I get the response "it seems that Trigger CMD is not linked to your Google account". I then need to sign in on my Android device and everything works again--for a couple of weeks.
