Recently updated to Sonos Controller 6.4.8 (build 331534191) on my Acer Android (version 4.4.2) tablet. Now any time I try to use the search function, I get the "Unfortunately, Sonos has stopped." message popping up. I cleared the cache and settings using Clear data for the Sonos app, reconnected to the existing system and problem still occurs. Uninstalled the app followed by a reinstall from the Google store and verified that I reinstalled the same version and build. Sometimes I can get a couple characters entered into search and the matches start to show before the app stops. It certainly impacts functionality. Am I alone in experiencing this problem? Any suggestions?
