Hi there,
Song skipping can be caused by many different factors. Most often, it is due to wireless interference from third party electronics.
Right now, we're looking into an issue that causes playback errors when streaming directly from the storage of iOS devices when there are non-Sonos AirPlay devices on the network and your iOS device goes into auto lock. We'll update this thread when we have more to share on this, but in the meantime you can get streaming going again by disabling AirPlay on any non-Sonos device on your network or by disabling auto lock in your iOS device's settings menu under display and brightness.
If you are getting song skipping from other sources, this guide has some great troubleshooting tips.
