About 1 month ago, I set up a new MacBook Pro using macOS Tahoe and my Sonos system worked but I could not add my music library (yet again!!!). I used Sonos support by phone 3 times in one week. The last call was 3 hours long without any success. My only option, according to Sonos, was to allow customer support that enters my laptop and they try to add the music library for me. I have done this before but I really do not like giving anyone access to my machine. I gave access and 2 hours later still no music library and I was told that the customer support person had to leave me because they had so many other people to help. I have not heard from Sonos again.
Last week I sat down and tried the 3 options available for adding the music library and amazingly it loaded! I did not do anything different than what myself and customer service had tried the few weeks prior but for whatever reason it worked this time. Maybe Sonos finally corrected the cause of error 913. What makes me frustrated is all the time I have wasted, not just now but over the years. If Sonos is working to correct this problem, let us know, don’t make us sit through frustrating and lengthly customer support sessions when you know you can’t fix it. Tell us Sonos is working on it and when we should try again with the hope of success.
