Sonos Notify with sound missing

Hi @DwayneMccoy, Seems to be a timer problem, sonos device type works in this manner : when a message arrives, the device check the status, if the status is playing, it takes the last track and append it after the message has finished, but to check the status the sonos must to be sending feedback, every time (like 4 or 8 hours I dont remember) a new subscription is launched, Smartthings have problems with timers, the timer just stop working, If no timer no refresh if no refresh no feedback if no feedback no real status. then when a messager arrives the status is playing and append the last track to play. I suggest first, go to sonos device and press refresh button, if you want to avoid this problems use a poll app set in 10hrs to refresh your sonos, try watch dog timer
