Hello Dante_Bailey,
We would like to see how we can help you with these missed notifications. Are you receiving no notification, or is it not making a sound as expected? If you go to Settings > Notifications is it switched on? Is it set to Banners? Is the ring/mute switch enabled on the side of the iPhone? Check out this link to check for Focus: Allow or silence notifications for a Focus on iPhone - Apple Support
"Allow or silence notifications from specific apps during a Focus
- Go to Settings
> Focus, then choose a Focus—for example, Do Not Disturb, Personal, Sleep, or Work. - Tap Apps (or tap Choose Apps), then do one of the following:
- Allow specific apps: Tap Allow Notifications From, tap
, then select apps. - Silence specific apps: Tap Silence Notifications From, tap
, then select apps.
Note: You can allow or silence notifications from specific web apps you’ve added to your Home Screen. (See Receive Web Push notifications from web apps.)
You can also turn on Time Sensitive Notifications, which allows all apps to send time-sensitive notifications immediately."
Get back to us with these details so that we have a better understanding of the issue, and we can go from there.
Cheers!
