Help with Focus on iOs 15 understanding please

Before iOs 15, i used 'do not disturb' without issue. I would set it, then when I wake up all my notifications were there on the locked home screen for a quick glance and I decide what to do with them.

Now we have Focus, Nothing appears on my screen like it used to as described above. No messages, no emails, no notifications, no nothing, I have to click through to find things that have arrived whilst i'm asleep.

How do I get back to that way as that's what I want and like.

I only use Do Not Disturb, no others like, Driving, Personal, Work, Sleep and no custom made ones.

Any help what settings I need within Focus to sort this please.

Thank you
