After following the workaround I found on the forum to add my local music library back after the app bafflingly seemed to simply delete it, I am able to access my library on the desktop app, but it simply doesn’t show up anywhere on the mobile apps.
We really need Sonos to step up here. The forum is full of people having the same issues. CLEARLY there is a problem here that needs to be addressed. Either that or the company needs to come out and state categorically “we only support online music services now, so if you put a lot of money into our hardware then we’re afraid you’re out of luck and made a poor choice.”
Seriously. This silence is not doing your company any good.
