I was asking because I have a notification today in one of my chats saying that e2ee was enabled. I didn't see the same notification in any group chats. Outside of that notification, it's not clear to me when things are encrypted.

Maybe the next step is a more obvious indicator.

I just checked this with a group chat I'm in, and it said that it was not yet enabled because one person has not yet updated.

After a few weeks, non-updating users will get a stern warning that Whatsapp will stop working until they update. Whatsapp does this with every version. They expire every few months.

Doesn't everyone in the chat have to have the new version of the app before it's all e2e?

I guess? Hence the indicator. It would be nice to know if someone switched phones and e2ee turned off, for example.

> Once a client recognizes a contact as being fully e2e capable, it will not permit transmitting plaintext to that contact

They do this to prevent degradation attacks.

Once your number had e2e support0, you can't switch to a phone without e2e. Notifications on key changes are switched off by default, but I hope they still warn you in the chat history. We'll see.
