I attempt to play my music outside from my Sonos amp to my outdoor speakers.  If I try to play just the outdoor zone for the outdoor speakers via Apple Music from the Sonos amp is skips through 5-6 track titles and never plays. 
 

The only way to play music in the outdoor zone is to group it with another inside zone.

i also went to play my music on Sonos today and it said no equipment under WiFi network so i literally had to set up all my zones today all over again.
