Hi SpiraSpirit,
Thanks for the post! We know it's important to be able to hear your notifications. As we understand it, unless your device is unlocked by Face ID, you don't hear most of your notifications; is that right?
By any chance, do you use an Apple Watch? If so, see if this might explain what's happening: Notifications on your Apple Watch
"If your iPhone is unlocked, you'll get notifications on your iPhone, instead of your Apple Watch.
If your iPhone is locked or asleep, you'll get notifications on your Apple Watch, unless your Apple Watch is locked with your passcode."
Also, you might double-check this setting if you haven't already: Use notifications on your iPhone, iPad, and iPod touch
To manage your notifications from the Lock screen or Notification Center:
- Swipe left over an alert or group of alerts.
- Tap Manage, then select from these options: Deliver Quietly: These notifications appear in the Notification Center, but don't show up on the Lock screen, play sounds, or show a banner or badge icon.
- Turn Off: This turns off all notifications for a specific app. To turn this back on, go to Settings > Notifications, select the app, and tap Allow Notifications.
You can also tap Settings to change your alert styles or alert settings for a specific app."
Keep us posted on the issue. If that doesn't help, be sure to include your iOS version in your reply.
Take care.
