I am not receiving notifications from apps until I open them.
Whatsapp and WhatsApp business are the only app that notify properly

I noticed this problem started since I was using iPhone 7plus of which it doesn’t show any app notifications at all until I restart it after an hour to two it stops showing notifications again

I taught it was the phone so when the phone got spoilt I started using iphone 7 and I am experiencing same problem with the 7 plus so I got new infinix hot40i still yet,enter image description here it’s not working properly

I already updated my phone and app I don’t have battery saver on,DND is off,i turned on background data for every app,I even reset my app preferences, cleared cache, uninstall and reinstalled the app still nothing pops up turned on all notifications on badges, banner and lock screen [[[enter image description here](https://i.sstatic.net/fzC1tZE6.jpg)](https://i.sstatic.net/TM0FE1bJ.jpg)](https://i.sstatic.net/W8ivdGwX.jpg)
