Re: Messages not showing on Lock screen
You may need to check you do not have "Do Not Disturb" / "Focus" turned on.
ie: Settings > Focus > Do Not Disturb
Else:
Wondering whether Message notifications were accidentally "muted" or "turned off" for the Lock Screen:
Eg:
Apple Support's online article:
Use notifications on your iPhone or iPad - Apple Support
Eg: says:
"To manage your notifications from the Lock Screen or Notification Centre:
- 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"

Re: (not) ... "giving me the ping"
Above linked article also says where to check :
"Change how notifications sound for a specific app
- Go to Settings > Notifications.
- Under Notification Style, tap the app you want to edit notifications for.
- Tap Sounds to turn on audio alerts for a specific app. For certain apps like FaceTime or Messages, you can select a specific tone to play with each notification from that app.
If your phone is silenced or the volume is turned down completely, notification sounds will not play."
