As you can see, there are 3 types of packages, how do you know which one is correct?
Open your WhatsApp and then click on the settings icon.
Scroll to the information row and click on it.
In this example im using second package (com.mbwhatsapp).
So I will click on the second option. If it shows you that you are using "com.whatsapp", then you should click on the first option.
Swipe until you find the download links.
3 download links will appear, as it says in the indication, options 2 and 3 are the easiest way to access the download of new updates.
In this case I will click on the link number 3
As indicated, you only have to wait a few seconds to access the download link. You just have to wait, you don't need to click something.
Once the time is up, it will redirect you to the download link. You just need to click on the download button.
Once the file is downloaded, you only need to install the downloaded file, it is not necessary to uninstall the previous version.
If it shows you a message that the application has not been installed, you need to make a backup of your chats, uninstall the WhatsApp you have installed, and install Fouad / MBWA iOS.
