iPhone 18 Pro with iOS 27 does not connect to CarPlay wireless when Bluetooth hearing aids are connected.

My new iPhone 18 Pro with iOS 27 does not connect to CarPlay wireless (or wired) unless I disconnect my hearing aids first. In fact, it won't even complete the CarPlay pairing process if the hearing aids are connected. I suspect this is a Bluetooth bug but it's a pretty annoying one and was not present with my iPhone 16 Pro. Has anyone else experienced this? How should I report it as a bug to Apple?

The hearing aids are Oticon Real but the change here is to a new iPhone 18 Pro - this all worked fine with iPhone 16 Pro, so either BT hardware or the software stack are broken.
