Linn DS disappearing
IOS 11.4.1 update has been reported causing general issues with Wifi connections, this is not only with Linn DS but with anything using Wifi.
If you go into iPod/iPhone settings > Wi-Fi and switch OFF Wifi for a few seconds then switch Wifi back on then Kazoo will then find your Linn DS/DSM's.
