Hey Kater_,
We'd be happy to help out if you're having issues with your notifications.
There's no reason that updating your iPhone should have had any impact on your ability to get notifications though. All the apps you've mentioned are third party apps though. Make sure each of those apps are fully updated in the App Store to get started. If they already are, try reinstalling them.
If that doesn't solve the issue, you'd be best supported by contacting Apple for support using this link given that this is unexpected behavior: Get Support
Take care!
