Any chance the app could be adjusted to allow for this work around?
I have the same issue with the Sonos beam muting TV volume to complete the TTS from the Life360 with States TTS updates and then it leaves it muted forcing to go into the sonos app to get it unmuted.
The above work around works for the rule machine TTS notifications.
EDIT: I just realized the Life360 Tracker is the one I'm asking for an update as it has the TTS selector on it, not the with States app.
