I had exactly the same problem, and I was trying to solve it for 2 days, in addition to setting trials I restored my device several times, but none of them solved the problem. I find a neat solution from Apple forums. I tried it and solved my problem.

- Download WhatsApp Business.
- Port your account over to WA Business (click continue after opening the app) without deleting the normal WhatsApp.
- Try to get someone to test send a few messages to your number. WA Business should push out the notifications.
- Delete your normal WhatsApp and restart your iPhone.
- Re-download and reinstall the normal WhatsApp from the App Store. Open the app and allow porting of info to take place.
- And there! Notifications should come in as per normal again on your normal WhatsApp!!!
- Delete the WA Business app if you have no use for it.

I started having the same issue as OP a few weeks ago, yes in 2021, this is still happening. Was so frustrating, tried almost everything that OP did but nothing worked. Decided to find some helpful thread and chanced upon this one. This helped with my issue! Thanks heaps!!So I finally got mines to work after much trial and error. I believe anyone who had Background App Refresh disabled and did the ios 14 upgrade may have hit an iOS bug.
I did the following.
1. With background app disabled fully close the WhatsApp app
2. Go to settings and enable Background App Refresh
3. Start WhatsApp and lock your phone. Have someone call you on WhatsApp or message you
4. Once your receive the notification, close the WhatsApp app completely
5. Go back to settings and disable background refresh
6. Start WhatsApp again.
after doing the about I am getting notifications again. What still does not work is the icon badge of waiting messeges.
Hope this helps!
