With apple intelligence enabled I am seeing a 10-15 sec delay in push notification. This is actually causing issue with my alarm system, door bells and 2FA requests.
I'm using iPhone 16 Pro. First installed 18.1 Dev beta 5 and AI and noticed this. When beta 6 was released it continued.
I put in FB15389900.

For me, updating to the latest iOS 18.1 beta 6 resolved the issue (I am on a iPhone 15 Pro).
Experiencing the same issue on 16 Pro Max iOS 18.1 Beta 6. The only solution I have found is to disable Apple Intelligence and only then notifications work as intended.

On iOS18.1, leaving Apple Intelligence on, this fixed it for me (at least with the Okta Verify app). Settings - Notifications - Summarize Previews - Turn ON (I had turned it off after upgrading...)
And ensure your app(s) in the list underneath it has it enabled too (I left them all enabled).
