Unable to update WhatsApp on iPhone, since it has been locked

Try this if you're experiencing an issue when you update or download apps from the App Store on your iPhone or iPad.

If you can’t download or update apps on your iPhone or iPad - Apple Support (IN)

If you still can't download or update apps

Contact Apple Support

You will need to contact WhatsApp for help with their software, this is not an Apple product. If you've been locked out or banned from WhatsApp, then there's a good chance they won't let you back in.

Here is a link to their help page.
