The past couple of days my uber pings do not have any sound. I've upped all the volume sliders and adjusted to maximum sound. Now all I get is a maximum sound warning. It is unsafe to be driving with your eyes glued to the phone screen. Definitely a safety issue. Has anyone spoken to Uber about this? I use a Samsung A8, but it is not the phone, the Lyft app ping works normally. There was an android system update today. I'm hoping my uber ping is back when I go out tomorrow.
