Sonos chief innovation officer Nick Millington says in an update published yesterday that he and his team are 100% focused on understanding and addressing issues with the Sonos app. Its the latest in a series of Millingtons posts sharing his teams progress as it tries to restore features that were left out of the apps controversial redesign in May last year.Heres what Millington, the original Sonos system architect who is tasked with fixing the app, has to say about the effort:The team and I remain 100% focused on two important priorities:1. understanding the root cause of every single customer issue, whether big or small, whether common or rare, and making sure the technical performance of the app meets or exceeds what you have come to expect from Sonos.2. closing gaps in the functionality and usability of the new app relative to what you enjoyed before, in a priority order that is as responsive as possible to the feedback we receive from you.Millington says users who have shared diagnostic information have sharpened the teams focus, leading to several improvements. In previous updates on the page going back to October, he has promised several features were on their way, such as alarm snoozing, better queue management, and playlist editing. He points out that you can once again snooze alarms, and says users can check the battery of portable Sonos Move and Roam speakers when theyre in standby. But the work has been slow-going and Sonos still hasnt added playlist editing back, nor the ability for a user to queue an entire folder from their local music library. According to Millington, both are on their way in upcoming releases.
