What's wrong with Shark? Can't they fix this app? Can only control ai robot with chrome book installation of app. Phone app will not work. Always gets to splash screen then crashes. Terrible support from shark not to have this functional. Ready to return this expensive vacuum. When will the robot fail? App will not stay running after last update. Now even crashes on Chromebook installation. Bad support. Will return. Recent update was welcomed. Worked for three days and now will not stay open.
