Power. The display switches into lower-intensity, and lower-powered, and less-touch-sensitive operation, and with the display refreshed once a minute.

It wasn’t that long ago that the display blanked.

They don’t have an app that does Lock Screens. That’s my point.

I understand. However, you may access the Today View from your Lock Screen (if you grant permission at Settings > [Touch/Face] ID & Passcode) and you may see the widget there.

You can see seconds if you wish. Simply add a click widget to the Today View.

We can't answer for Apple on a user-to-user site......we are all users......just like you.

Apple will acknowledge receipt of your feedback, but they will not respond further.

That would be a good question to ask Apple here: Product Feedback - Apple
