Carplay ********

******** is a third-party app; it's not an Apple app. It's likely that ******** needs to be updated to work with iOS 18. Since iOS 18 is currently in beta, ******** cannot release an update that would make it work with iOS 18. You will have to wait for iOS 18 to be released and then wait for ******** to release their update for it to work properly.

Besides, if there is an issue with a third-party app, you should really tell the developer of that app so they know, and can fix it.
