Sonos software is so bad - in particular using local libraries - that they should be refunding peoples hardware purchases.  I ended up buying a NAS drive when the last ‘improvement’ removed the ability to stream my library from my phone.  I own a lot of music and wanted quality speakers - why is it the F***wits at Sonos don’t get that this is a common situation? I badly regret investing in Sonos, now I cant afford to replace them all with speakers that have software that actually works.  What is the legal situation whereby these cowboy criminals sell you expensive hardware then through design or complete incompetence remove your ability to use them.  My Sonos speakers are not fit for purpose.  I should be entitled to a refund.  Why is there not a class action against Sonos for rendering their product useless?  All they are interested in is Ad banners to sell you more product and streaming services.  Best advice to everyone (particularly if you refuse to be bullied into buying streaming services) is get rid of this shit product and never buy Sonos again.  Make sure you tell everyone on social media what this company is like and what they are doing.
