Like many others, I’ve had issues with my music library (WD MyCloud NAS) randomly disappearing. It’s seems to frequently occur when I take my Iphone or iPad out of Wi-Fi range and then return, causing the app to attempt to “find” the library again with random success. On the other hand, the web app and/or the desktop app always has access to the library. It probably doesn’t help that I have two Sonos systems (a Connect and a Port) in different locations so the app appears to take a lengthy time to reconnect to one or the other.
Has anyone found a workaround to this issue? I reset the app numerous times a day, with hit or miss success. I’m not a tech expert, but it seems the problem resides in the design of the app where everything is run through the cloud. Could this be a Sonos server issue or just a poorly designed app?
