I am writing this as a some what measure after spending almost 2hrs on the phone with 2 different customer service people.  The first was helpful but didn’t resolve the issue, the 2nd was absolutley uesless and dismissive. Wow.

The short… I’ve had sonos for years, I have a large DB of songs that have played fine.  But after updating to 15.3 its a fire in the whole.  For me the problem seems random.  I can see and play most of my songs but many indicate that they are “not encoded correctly”.  Also MANY of the songs don’t even show up in search, even though they are only my NAS and can be played if accessed directly.    I’ hav deleted files, and uploaded new versions and nothing gives.  Its just random and thats the worst part about it!  My song collection is largely from CD rips and purchases from various sites.  I do not use apple.music.   The punch line… all of this was a none-issue before upgrading to 15.3

I have an open ticket number #nremoved] and I would appereciate any help that you can provide.

Thanks
