I am no longer receiving audible text alerts, nor does my phone ring. Here is what I've tried/figured out so far: 1. Do not disturb is off 2. Bluetooth is off 3. Music plays 4. When text/call is received, notification shows on sleep screen as expected. 5. When text/call is received, phone vibrates as expected Steps I've taken: 1. Turn ringer off and back on via switch on side 2. Confirm via settings that I can hear the ring/text preview 2. Reset phone (power off and back on) 3. Restore phone via iTunes What troubleshooting steps am I missing?
