I recently upgraded to a new desktop which hosts my SONOS music library. My system is little more than a set of bricks currently,  and so far three separate support chats or calls have ended up in the support person mysteriously disconnecting for no reason. I can only assume they do not want to deal with the issues, but I am increasingly frustrated as an early adopter and long time user of SONOS.

Here are my issues:

1. Music library shows the folder on the old computer that no longer exists. When I try to remove it, it simply comes right back.   
2. When I try to add a new folder to the library, the folder is never added. There are no error messages. I have tried adding the local folder and set up a network share and tried that to no avail. I have tried disabling my firewall and Malware Bytes, which also did not work,
3. My Play:1 does not show up on the PC app at all, and says “incompatible” on my android phone app. Attempting to update from both phone and PC ends up in an error every time. Generic “There was a problem during the update of your Sonos system”. I have attempted to restore to default on the Play:1 but unplugging and holding play button while plugging back in and waiting for the green flashing. It has made no difference.

I know it is a lot to ask the community when Sonos support seems beyond unsympathetic, but downright rude. But here I am. Does anyone know anything else I can try? Is there a way to restore everything to a beginning state and just re-setup from scratch? I am open to just about anything at this point. Thank you in advance for your assistance.
