I've noticed some interesting CP behaviour with iOS 13 beta 7:
- You can set favourites for Music, Maps and Phone individually.
- Not sure if it's a bug, but I added my Maps favourite while TomTom was the active mapping software. If I close all running apps directly on the phone so no mapping software is running, and press the assigned Maps favourite button in the car, TomTom always starts. In fact it doesn't even appear to start on the phone, it's just there in CP. Really cool and useful
- So far iOS 13 is rock solid from a CP perspective. The 3 issues I had with audio failure, random connection failures and disconnects, don't appear to be happening anymore

Update 270819 - the audio failure issue is still present on iOS 13. CP connected correctly as normal. It connects really quick with iOS 13 btw. Music started playing on my phone and not the car. I could still control all CP functions from the car, just no audio from the speakers. Reset wifi and all working fine again.
