Spotify, Google Home, Video Block

Afternoon All, I'm finding that turning on Video Block is blocking Spotify entirely, that is both audio and video streams. We use Spotify Premium to play music (through Google Nest minis and Sonos) throughout the house. If I have Video Block on to the kids group, it also stops them playing music... Is it just me, or is this others have noticed. Ps. If I turn Video block off, audio works again...
