Whats worse is that if you own a google home mini and turn off the web and app activity it essentially becomes a useless brick.
For most commands literally everything is on the lines of "Sorry I don't have enough access to perform that command. You can change this in the Google Home app". Simple stuff like "Play some music" and "Whats the weather like?" is blocked.
I just wish there was more fine grained control over exactly what I give access to.
