I have downloaded the JBL Connect app (Samsung S7), upgraded to JBL Connect+. Does nothing, except change name of the JBL Charge 3 and do upgrade again. How can I access the “turn off alert sounds”  ????? BTW: the app stays most of the time in “Discovering” mode (although BT works fine). Please help

Hi, I am using Android (GS7). Upgraded to Connect+, the app does not discover the Charge 3 at all (Bluetooth works fine). I did the upgrade because I need to disable the notification sound (terrible and loud). But, no luck at all. :C
