Grouping is currently not working--the first speaker in the group works and the others are silent. They show as being in the group and playing. They do not drop from the group.
I've searched previous "group play not working" threads. I'm on the newest update.
I've tried various combinations and sources. It has always worked before. The issue is not Wi-Fi related, as all my speakers are hard-wired. I can play on each of the speakers individually.
I submitted support diagnostics after replicating the issue (using my Kitchen and Living Room Sonos speakers). The confirmation number is 1144043752.
