I have the exact same issue. I’m using YouSee Music as my streaming service in Denmark. When you try to do a search you got “ Ups an error occured - check the service. “ When checked it is up and running. The new app is totally useless with out the search function. Another thing is that you can’t edit the queue. And the last thing which happes several versions ago, is that you can’t cotrol the volume from the psycical buttons og the iPhone.

Same issue

search doesnt work on Music Library

cant pin Music Library as a source

app is for cloud based spotify users now not for people with music collections

volume control is useless

in fact its all gone backwards whereby you have to have your phone always with you now there are no controllers

feel the heart has gone from the product since i bought in 2007 and having done £4k upgrade

yes, “please be patient, coming back soon”.

In the meantime, we would all like the S2 app back. please let us have it again.

Sorry ? Who asked who needs to be patient ?

There have been one or two statements to that effect. That “we” the customers are supposed be be patient.

Not sure if this helps. We were having the same problem after installing the new Sonos Ap on our iPhones. Search function found…nothing. We use Napster as our streaming service. The Sonos search function only worked with Sonos radio. The solution was to go open  and update the  Sonos desktop controller on my PC. During that process of updating and signing in a prompt popped up with “Re-authorize Napster”. After reaurhosizing on the desktop controller the search function returned to all our devices. 

Every time I open the App, the search function is unable to find any of my local or my streaming service. I get a blanked screen for about 5 seconds and then ‘sorry, something went wrong’ pops up at the top of the screen.

so I have to go to account >content service >my service>reauthorize and then reauthorize all of my services for it to work. 
this is a 2 minute job -Every time- and it Ruins the experience completely. 
 

But let’s face it, these forums are just for gas release right? 
Sonos are not reading them, they aren’t doing anything to fix these issues. Just letting us bitch while they sail around in their yachts (bought with our money) with their Bose systems bluetoothing Spotify. 

What we need is for the music media to get back onto this and update their pages to say that PROBLEMS ARE STILL RIFE TWO MONTHS AFTER THE NEW UPDATE AND PEOPLE ARE STILL VERY UNHAPPY.

Then we might see another effort.   Till then, we just get a small warm glow in here from our own hot air and go back to Air-Playing our songs to listen.
