On iOS 18 beta 3 on my iPhone 12 pro max and can also confirm that CarPlay has frequent random freezes and hangs when trying to use Spotify and pandora. I even reverted to iOS 17 and CarPlay worked as it used to without a hitch. A week or two prior to beta 3 i cannot remember having a single issues with CarPlay on iOS 18 beta 2 or 1. This is new and needs to be fixed. CarPlay is the issue. Not the apps trying to be used in CarPlay. No restrictions were set in any area of my settings app. This is strictly an issue with CarPlay in iOS 18 dev beta 3. rendering CarPlay pretty much useless in some scenarios. Not sure how this hasn’t been fixed yet. Get on it, Apple.
