My mostly Whatsapp notifications are delayed when My mobile is not in use or in idle. When I open WhatsApp then it shows messages and calls. And I received no WhatsApp call when screen turns off. When I open WhatsApp it shows missed calls. I have performed all tricks like app refresh is on, No Internet issue, factory reset etc
Hey there, engrsalman.
Welcome to the Apple Support Communities! Thanks for posting about some notifications not showing up as expected. We'd be glad to see how we can help you out.
So the first step we'd take is to make sure that your device is running the latest version of iOS, and to do that, you'll want to follow the steps in Update your iPhone, iPad, or iPod touch. If you're already fully updated to the latest version, you can move on from there by ensuring that all of your apps, especially WhatsApp since that's the app where the issue is present, are updated by following How to manually update apps on your Apple device. Double check that the settings for the notifications for that app are correct in Settings > Notifications for that app and any others affected.
Let us know what you find out.
Be well.
