This is not the expected behavior. Our engineering teams need to investigate this issue, as this might indicate an issue with iOS 18 Beta.
We would like to see a Feedback report about this with some diagnostic logs in order to investigate why you are seeing this behavior.
First, please go to https://developer.apple.com/bug-reporting/profiles-and-logs/ and follow the instructions for APNS (Apple Push Notification Service) to install a logging profile on your device.
Once that is installed, recreate the problem, and then follow the instructions at the above link to trigger a sysdiagnose.
Once you have that, please file a Feedback report using the Feedback Assistant Attach the sysdiagnose and a sample project if you have one, and reproduction steps you have taken.
