Thankfully the ban isn’t permanent.
In the past couple of years, WhatsApp has risen to be one of the most widely used communication services in the world. The app itself has also been one of the top apps installed on any smartphone but some power users still prefer to have more features on the native WhatsApp app.
This is where third-party WhatsApp clients come in. Popular alternatives like WhatsApp Plus offers more user-requested features compared to the original WhatsApp client. But the problem is that these apps aren’t authorized clients (WhatsApp doesn’t have APIs that third-party apps can use), meaning that they’re simply hacked versions of the app.
Which could pose to be a big security risk, especially if you’re using WhatsApp to transmit confidential and important data. This is the reason why WhatsApp has started banning users that use third-party clients.
Fortunately, though the ban isn’t permanent, and you should be able to continue using your WhatsApp account once your reinstall the original app. The company is recommending that you enable your backups so it’s easy to retrieve your chats just in case the inevitable happens.
