FWIW, I had issues with my Google Home Mini with the Web Cache app turned on.
I was testing out Web Cache and the specific issue I'm having is if I ask Google Home to play something like news, music from Spotify, etc., whatever it's playing cuts out randomly after a few seconds.
Problem disappeared if I add a bypass rule for the GH Mini in Untanlge, or if I turn off Web Cache. I opted to do the latter.
