This is what it feels like. But if it is Doze then it’s really broken - because it happens when my phone is plugged in and charging!

I don’t think that’s it - the notifications are getting to my phone, Android is just not showing them to me. In the example today in my post - the notifications were timestamped 8 and 6 minutes ago, but there was no alert for them. And, I have good connectivity - especially today’s example, sitting at my desk connected to my home wifi - which is good.
