Hi ​@MusicSource22 

Welcome to the Sonos Community!

Sorry to hear of this issue you are having with playing some of your playlists.

To get to the bottom of this issue, I recommend you get in touch with our technical support team who have tools at their disposal that will allow them to give you advice specific to your Sonos system and what it reports.

I hope this helps.

This is so disheartening to read. I contacted tech support 2 months ago. Was told Level 2 would contact me to help further, and had to schedule time to receive the call. 

That "help session" with Level 2 consisted of the tech telling me "it's on the list to fix but we are waiting for the engineer to pick it up."

​@MusicSource22 - please let us know the outcome of your call with tech support.

Try one of my apps (see profile), see if they can play them.

This is where I *would* post a gif of Jar-Jar saying "Muy, muy, I LOVE YOU!"

But I will spare you that, and just say that I've never been happier to pay for software when someone else (ahem, Sonos!) should have been providing it for free.

And I'll be spending more to add it to the other machines in my house, because IT WORKS! I CAN FINALLY USE MY PLAYLISTS! WOOHOO!

Bless you, sir! I know I searched for an alternate app months ago, but never found one that worked for Android. Is this a new platform for you?

Thanks for the feedback! Yes, the Android version was released just a couple of weeks ago, it’s a new platform for me.

I'm affected by same issue on my Samsung S24. Sonos please fix this. It's really annoying, I don't want to recreate my playlist from scratch.

​@honeyglazedbadger - please see the response in this thread from ​@controlav .

I’ve downloaded his controllers for both iPhone and Android. 

They are worth every penny!

I contacted sonos support for this. The first layer of support couldn't figure out the issue. Suggested silly things like restarting my phone lol. Ultimately they referred the case to a higher level support technician. I figured out that if I remove enough songs the playlist begins to work again. If i copy the playlist the same issue persists on the copied playlist. I feel like like a playlist gets a song removed but it doesnt get removed properly and breaks the playlist until you remove songs up to that point...

My Library suddenly disappeared and was unable to re-add it.  Spent 4hrs on the phone last May and finally the Level 2 tech figured out the issue.  Last weekend BAM.  Library MIA again and wont re-add.  After watching level 1 tech flail on my MAC i began reading him Google posts about the issue. He gave up and bumped to Level 2.  I gave her some pointers on where to look for things that don’t match the “Itunes path” My NETBIOS has a different name for my mac.  After a couple of reboots she was able to successfully add the Library AND playlists( only 3 hrs this time.) Unfortunately not ALL the songs in the playlists made it and started getting “Unable to locate” errors.  decided to re-index .  Then BAM, now all my playlists are missing again.  I’ve carefully gone through all the Music folders and .XML files to make sure they are in path.  I’ve pretty much resolved that if I want to play a playlist, I’m gonna have to use my BEACH JBL 5s in the house.  I’ve been Sonos fan for years and have multiple components.   I’ve never had any issues until the update from HELL.  JA  

I just discovered the problem: all my playlists have disappeared from the home page. I can't find them, and I can't create new ones. Another SONOS bug.

I’m curious about what Sonos Support said, when you called in?

I don’t have lots of playlists, but none of the ones I do have disappeared on my system. 

Just looked at my Sonos here, local music library and locally saved Amazon playlists are still available.

Always a good first step is a full system refresh. Power everything down, power up router, wait a minute or two and power up your Sonos.
