In my tests, calling NEHotspotConfigurationManager.removeConfiguration(forSSID:) disconnected from the accessory's AP again.

I observed the same for iOS 18. There is a partial workaround: when authorization status is .notDetermined, request only .provisional authorization when authorization status is .authorized (i.e. after the user chose Keep), request [.alert, .badge, .sound] This way you at least get support for badges and sound, but it is still bad because the Lock screen and Banner settings will still be disabled and I think there is no way to re-request them programmatically. Unfortunately this makes provisional authorization kind of undesirable for many use cases.
