I am able to see other HTTPS related activity of apps on the web proxy fiddler, but how is WhatsApp or other end to end encrypted services manage hiding their client to client communications from fiddler and wireshark ?
I do understand few things from the post https://www.whatsapp.com/faq/en/general/28030015 but not sure how these things are hidden from network monitors
Is there a visible network activity happening at all behind which I am unable to see due to the poor web proxy configuration ?
