Disable whatsapp notification in night

Hello Whatsapp_Notification,

Thanks for choosing the Apple Support Communities. You can use Apple features like Focus to silence notifications when you'd like. To learn more about that follow the steps below.

Use Focus on your iPhone or iPad - Apple Support

"Turn on Focus

1. Go to Settings > Focus. 
2. Tap a provided Focus option—like Do Not Disturb, Personal, Sleep, or Work—then tap Customize Focus.
3. Set up your Focus. You can select allowed or silenced notifications from people and apps, connect your Lock Screen or Home Screen, have this Focus turn on automatically, and add Focus filters.

You can also enable Time Sensitive notifications from apps, which allows apps not in your allowed list to send notifications marked as Time Sensitive.

You can also turn on Focus from Control Center. Just open Control Center on your iPhone, or on your iPad, touch and hold Focus, then select the Focus you want to turn on.

When you set a Focus, the icon appears in the status bar and on your Lock Screen, and your status is automatically displayed in the Messages app. When people try to send you a message, they'll see that you've silenced notifications, but they can still notify you if it's urgent.

When you use Focus on one device, the setting is automatically applied across your Apple devices that are signed in with the same Apple ID."

If you're requesting a feature within the app itself, we suggest reaching out to WhatsApp. Here is how.

Cheers!

Do Not Disturb setup has been made much more flexible, but this has come at the cost of much more complication. To get it working again, do these steps ONCE:

• Tap Settings
• Tap Focus
• Tap on any Focus settings that you will never use and remove them (you can add them back later if you change your mind, and even create new, custom ones)
• Tap Do Not Disturb
• Tap People
• Tap Allow Notifications From
• If anyone is listed who should not call you when DND is on delete them; if you don’t want any calls from anyone, any time, delete all people
• Tap the dropdown next to Allow Calls From and choose Allowed People Only
• Next tap on Apps, then Allow Notifications From and don’t add any apps unless you want notifications from them when in Do Not Disturb.

All of the above is a one-time setup. After that, turn DND on or off with the Control Center Focus button. You can optionally set one or more schedules by going to:

Settings/Focus/Do Not Disturb/Set a Schedule.
