I updated my Gmail app to the latest 5.0 version and now my gmail notification ringtones DO NOT work!!! and the usual hitting of the menu button on my Samsung Galaxy S4 has NO function!!! NOTHING happens!!! it DOES NOT bring up the label setting like it used to, the ONLY settings available is general settings in the upper left corner and it is NOT there!!! the help SAYS you CAN change it but DOES NOT tell how and the usual is NOT the way to do it!!!
