The conversation between human and AI assistant.
Can someone access your WhatsApp messages on your old phone, even if they have a different number? Can they also see current WhatsApp messages being received or sent?
What about current messages being sent or received on WhatsApp, can someone else see those?
Only you and the person you're messaging can see the messages being sent and received in real time. They won't be able to see those messages on an old phone that is no longer being used.
