"Feature unavailable" in the Facebook window

Your Facebook account doesn't have full access to the business portfolio, or the portfolio is still being verified by Meta.

Fix: Ask the owner of the business portfolio to give you full (admin) access in Meta Business Manager, then try again.

The number shows "Not registered"

Meta isn't sending this number's messages to NexusBot yet.

Fix: On the WhatsApp settings page, click Verify with Meta. If it still shows "Not registered", click Reconnect.

It connected as a Cloud API number instead of the Business App

Meta only offers the Business App option when the number is currently active in the WhatsApp Business App on a phone.

Fix: Make sure the number is open and working in the WhatsApp Business App (not the normal WhatsApp app), update the app, then remove the connection and connect again.

Messages stopped arriving

Fix:

  1. Go to Settings → Channels and check the WhatsApp status. If it says Needs reconnecting, click Reconnect.
  2. Click Verify with Meta.
  3. Send a test message from another phone.

My reply won't send

The 24-hour window has probably closed. See The WhatsApp 24-hour window.

Something went wrong in the Facebook window

Pop-up blockers can stop the Facebook window from opening.

Fix: Allow pop-ups for app.nexus-aurora.com, refresh the page and try again. Use Chrome, Edge or Safari on a computer.
