Missing Notifications even though notifications have always been on.

The other day, notifications from apps stopped showing up on my phone. I’m still getting the important ones from iMessage and Phone, but everything else has stopped. I checked the apps I want notifs from, and all the notifications are still on. I followed a Reddit post and shut off my phone, but nothing changed when it came back on. I also checked and did the IOS 26.2 update. It fixed the problem for a few hours before all notifications from the other apps stopped again. This is extremely frustrating and annoying because my phone has never done this before. I’ve had this iPhone 14 Pro for about three years now. I haven’t dropped it in water or dropped it a lot. Any ideas?
