What to do if the WhatsApp messages do not arrive until the application is opened

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.

  • Clear cache memory phone (Android). The cache is a collection of small files that help speed up the running of apps, while also burdening the apps with accumulated files. Therefore, the notification may be delayed from the cache and you should delete it from time to time.

IOS users don't need to clear the cache as the system will do it for you; however, if you are still worried and want to clear the cache deeper then deleting the app is the best choice for you and further details on reinstalling WhatsApp will be listed in Solution 5.

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.
