What you need to do to receive WhatsApp messages normally

You can try one of the following suggestions, and if that doesn't work, go ahead and try another one. The most common reason why you can't send or receive messages on WhatsApp is because of a weak internet connection.

Let me know if you've solved it with any of these tips!

One of our users advised us to do this:

Go to App → Whatsapp → Authorization. It will show the default authorization list. Now choose the icon "|" at the top right and select "All permissions". Scroll down and find “start at startup”. It should only have an Ok button. How many times do you ok, keep showing the same.

But after this my Whatsapp never went into sleep mode and I started seeing notifications. But I wonder that they could have set a recognition or a slider to know if it is set or not. Perhaps too trivial user experience factor. There are a number of other permissions we can set. They are not shown in the default set.

This has nothing to do with the model or brand of the phone; it's a feature of the operating system, I believe.
