I've been using my iPhone to listen to music in my car via USB for years... I've had no issues until I updated to iOS 11.3 on Thursday and now the phone charges but I'm unable to play music from the Music app. I've tried resetting/erasing the entire phone, using different USB cables, etc. I used a phone that still had 11.2.6 and it played music right away. I just got off the phone with support and they pretty much told me there was nothing they can do about it. Is anyone else having this problem?
