New Linn iPhone app
I noticed Linn have dropped the Kazoo DLNA/UPnP/Home control point app.
The new app is iOS only at the moment - I dion't know if there will be a macOS version - and it's just called Linn.
It has lots more Linn-specific bells and whistles, but still works with my Minimserver/RPi/Sonos setups. And it looks beautiful.
There have been some complaints about instability on the App Store, but it's been fine so far on my iPhone. I'm very happy with the upgrade, although I hope they provide a macOS version soon.
