Where to start? We have both children's speakers linked as a group to cast music/ stories to them at bedtime. Out of nowhere the app no longer allows us to cast to the group. Tried restarting the speakers, but no success. Same problem with the app on my phone, my partner's phone, and my iPad. Also, for some reason, music now stops mid-song for no reason. It still shows as playing in Spotify (time counting down) and shows as connected to whichever speaker we're playing on, but no sound 🤷‍♂️
