It’s like I subscribed to the “weird bug of the day” club when I decided to put Google Assistant on Sonos. Today I can’t pause playback of my playlist on Sonos. Google can start and pause music from other sources on my Sonos speakers (can’t say “stop” any more, that was the weird bug of a previous day). But it can’t pause playback of my Sonos playlist from my local library - since yesterday it says “sorry, I can’t contact Sonos”, but only when attempting to pause playback of my local playlist.
… and now it’s back after the third test this morning. Sigh, it’s something every day.
