My iPhone is not recognizing WhatsApp as an official app

You’re seeing “Untrusted Developer” or “Unverified App”

This can happen if:

• You installed WhatsApp from a source outside the App Store (e.g., sideloaded or TestFlight beta expired).
• You’re using a cloned or modded version like WhatsApp++.

Fix:

• Delete the current version.
• Reinstall from the official App Store: WhatsApp on App Store

No idea what that means, please describe your issue.

Please read the following article then post back with your question –

Please explain what exactly is happening?

How are you trying to access WhatsApp?

Did you download the App from the App Store?

Please provide as much detail as possible.
