We are actively investigating the issue where the system tray closes on its own. Once we have more information about this, we will share. Many apologies for the frustration this has caused.

We've been seeing this with Spotify users, but there is a work around until this is fixed. If you launch the Spotify app and disable lock controls within settings (controlling the speaker even when your phone is locked), it should prevent this. If you really like the lock control feature, users have found that making sure that not keeping the Spotify app and the Bose app running at the same time also helps.
