Remember that this package will replace the original WhatsApp, try to uninstall the WhatsApp that you have installed, without first having made your local backup.
If you already have an old version of Fouad iOS WhatsApp installed, just install it on over of it, it is not necessary to uninstall the old version.
Sure in many videos you see that they are uninstalling the previous version to install the new version, but if you do not perform the steps to restore the backup correctly then you will lose everything. To avoid problems, follow point 2.
It can be a bit annoying, but go ahead if you want to support the developer.
Just have to wait a few seconds to access the download links.
If the link above doesn't work (due to MediaFire blocking), try this link.
