How do you turn so not disturb off??

Hello LAB56,

Thank you for reaching out to Apple Support Communities, and we'll be happy to help in any way we can. We understand you're having issues with turning off Do Not Disturb on your iPhone after the update. Have you tried restarting your iPhone? This simple step resolves a multitude of issues: Restart your iPhone - Apple Support

"How to restart your iPhone X, 11, 12, or 13

1. Press and hold either volume button and the side button until the power-off slider appears.
2. 
3. Drag the slider, then wait 30 seconds for your device to turn off. If your device is frozen or unresponsive, force restart your device.
4. To turn your device back on, press and hold the side button (on the right side of your iPhone) until you see the Apple logo."

If that doesn't help, do you have any restrictions set? If so, this would explain why you're unable to turn it off. You can check for this as described in this article to see if that resolves the issue: Use parental controls on your child's iPhone, iPad, and iPod touch - Apple Support

We hope this helps.

Cheers!
