Over the past couple of days, I have lost the ability to adjust the volume on the Sync3 audio system in my 2020 Ford Escape Titanium when I have my iPhone plugged into the system. The CarPlay system runs perfectly, save the ability to change volume. When I spin the volume knob, the screen shows a volume adjustment for "Prompt Volume" and the level changes, but has no effect on the audio level. Rebooting the car system (holding POWER and >>|) and the iPhone do not fix the issue.
Any ideas?
