Hi eren1319
welcome to the Apple (user-to-user) Community!
Re: Not getting any non-apple notfications
Please check that you do not have notifications "silenced":
Allow or silence notifications for a Focus on iPhone - Apple Support
_____________________________________________________
Else: Wondering which iOS version is installed on your iPhone.
If you do not have automatic updates turned on:
Please check Settings > General > Software update to see if there is an update you may need to install.
(The screen shows the currently installed version of iOS and whether an update is available.)
Eg: About iOS 17 Updates - Apple Support says iOS 17.3 is the latest version ...

If your iPhone is already updated to the latest version:
Try restarting your iPhone (eg: deletes temporary files, re-establishes connections, and more, often restores order): How to: Restart your iPhone - Apple Support

If you find you still need help, try browsing through Apple support's online recent articles (links below):
Use notifications on your iPhone or iPad - Apple Support
Eg: says:
"Change how notifications appear
Go to Settings > Notifications.
Under Display As, choose how you want notifications to appear on the Lock Screen"

Re: stopped getting notifications from discord or outlook
Am not familiar with discord and outlook:
Change notification settings on iPhone - Apple Support
Eg: says:
"Receive Web Push notifications from web apps
You can receive standard Web Push notifications from a web app
when you add its website icon to your Home Screen.
Web Push notifications can keep you informed of activity in the app.
After you subscribe for push notifications within the web app, the app can send you notification alerts
and badges similar to the ones you get from other apps on your iPhone."
Hope something here helps you solve the issue!
All the best :-)
