IPhone 14 – Background Message Delivery Issue

I use an iPhone 14. WhatsApp, WhatsApp Business, Instagram, and Slack messages are not delivered reliably in the background. Messages arrive after I open the apps. This happens on both Wi-Fi and mobile data. I updated iOS, restarted the phone, checked Background App Refresh, and reset Network Settings, but the issue continues. Please help diagnose the background connectivity and push notification issue.

Same here. iOS 27.0.1 on an iPhone 17 Pro Max with AT&T. I’ve never seen anything like this. Happened after last update.

I will see badges for apps with notifications if phone is unlocked and I am scrolling the Home Screen, but get no alerts, no sounds, no banners when I’m in an app or phone is locked. Nothing on my lock screen.

Only get/see/notice notifications (badges on apps) when I unlock my phone and am on the home screen. Hopefully they can fix this. Missing a lot of calls and messages.
