Hi ruthannlehane
welcome to the Apple (user-to-user) Community.
Re: Notifications Silenced?
In Apple Support's article:
Use notifications on your iPhone or iPad - Apple Support
if you scroll to:
Manage notifications
says:
"To manage your notifications from the Lock Screen
or Notification Center:
Swipe left over an alert or group of alerts.
Tap Options, then select from these options:
Mute for 1 Hour
Mute for Today
View Settings
Turn Off
You can also tap View Settings to change your alert styles or alert settings for a specific app."
NB: Seems notifications may have been accidentally turned off there ?
Further down, article says:
"Change alert styles
- Go to Settings and tap Notifications.
- Select an app under Notification Style.
- Under Alerts, choose the alert style that you want. If you turn on Allow Notifications, choose when you want the notifications delivered—immediately or in the scheduled notification summary."
There are more "notifications" tips in the article itself.
All the best :-)
