Use Do Not Disturb with Focus on your iPhone or iPad - Apple Support

Hello Anilablond!

1. In the top right corner of your iPhone, swipe down to open the Control Center.
2. Tap on the bubble that says “Focus”. This bubble is located at center screen underneath where you turn you Wifi on and off.
3. Now, at the top of the list, you will see the Do Not Disturb Focus. It will be white. Tap it, and it should turn black like the rest of the Focuses.

I hope this is helpful. Good Luck!
