Notifications for Locked Screen? Or Always.

For a particular person or for all

Notifications are always for incoming email, text, calls, etc never for outgoing

This indeed is rudimentary --> Change message notifications on iPhone - Apple Support

I have an iPhone X. I was not having any problems getting text alerts (that is, I receive a text and have an audible alert that I have received a text). But now that does not always happen. Sometimes I get an audible alert, and sometimes I don't. I have tried everything I can think of to fix this. It may have corresponded to when I got my iPad2020. The alert notification sometimes is audible on the iPad, but not on the iPhone. I have tried to change the Settings on the iPad as well, with no luck. The other possible complicating factor is that I have two Apple watches. I usually have the sound turned off on the watches, but I have tried turning it on and still no luck, although sometimes I get an audible ding on my watch but not on my phone. I have missed some very important text messages because of this. I would be grateful for any advice on how to fix this. Thank you!

I’m having the same issue with my iPhone X. Sometimes I get the text alert (chime sound) and sometimes I don’t. I will have my phone sitting right beside me and no sound/alert, just shows up on locked screen. I’ve made sure the sound is up and nothing set for silent. So strange...

I don’t get text sounds when my iPhone 11Pro is locked. I have checked sounds, so not disturb, software update and attention awareness is off.
