Thanks for the reply. I search every now and then and all I've found of late was a cryptic post on Sonos user forum where a supposed HEOS user found changes to the app "crippling" and wanted to know what to buy to change his whole system to Sonos. Of course he didn't elaborate.
None of my clients have left angry messages so I'm thinking it's business as usual, at least for now.

My wife says I can't do sarcasm. She says I just sound like an a$$hole.
