Do Not Disturb keeps coming on

My phone keeps entering do not disturb mode. I do not have any schedules or automations set. Focus is not set. I know how to turn it off, but every time I stop using my phone, it goes back to do not disturb. I need to get notifications and this is making me crazy. Why does it keep defaulting to dnd? I have tried powering down my phone, and it didn't help.
