Had a few issues with v4.0 with my NAD M50.2, but v4.05 seems that have resolved the issues. And I like the upgrade, the blueos iPad app actually looks nice now.
Bluesound "upgrade" 4.0
Anyone else having problems with the new Bluesound update to version 4.0? I have had years of fairly reliable operation until now. Did all recommended resets which work for a little while then a lot of buffering, favorites missing and different issues depending if you're doing the desktop app or android app. Quite frustrating...wish they would have left the older version and not released the new until fully debugged!
