I maybe the only one but wish Google let us set a schedule for turning off and on always on display.
You can't do this on a Pixel? On my Samsung device I have the ability to schedule it, maybe you're looking in the right but wrong place?
For me, I go to the Always On Display toggle and to set a schedule I touch the words Always On Display, not the toggle the words, and that takes me to the settings for that kind of stuff.
Does setting a DnD schedule turn it off when in DnD mode?
Also how do I delete the info in red circle?
To add weather info you have to long press the home screen tap home screen settings then make sure at a glance is turned on. Then tap the cog wheel and select what you want shown. As for the date, you can't remove it.
