Hello! Two of the customers of my app have reported this same behavior (IONIQ 5 Companion). Both reported it happening with third party wireless CarPlay adapters, and in both cases the issue was only resolved by rebooting their iPhones. Please see: https://github.com/gburlingame/ioniq-app/issues/33 and https://github.com/gburlingame/ioniq-app/issues/28 for screenshots. These are two engaged customers, and I'm glad to work with them to help understand and resolve whatever is happening.
