Some tips:
β’ Update WhatsApp to the latest version, stable or beta.
β’ In the VPN settings you must select official Whatsapp, not MBWhatsApp.
β’ Use the split screen or floating app, if you don't have another device you can do it from a computer with Phone Link (To scan the QR code, Install from Store), or use WhatsApp Web if you have sent the screenshot to a contact.
β’ No need to disable location or use a proxy after linking.
β’ Don't take more than 15 seconds
Take advantage while you can.
