not possible to initialize encrypted conversation

[rynnon]

OMEMO encryption actually works for me. The issue is that I can't send encrypted messages until the person I want to talk with sent me an encrypted message, even though I already had encrypted conversations with them in the past.

Profanity command:

/omemo start contactX@some-jabber-server.org

// profanity output:

OMEMO Session started.

// I send a message:

Last message was sent unencrypted.
me: hello

//contact sends me a encrypted message message (contact is actually me with a different account from my
phone running conversations)

contactX@some-jabber-server.org: hey!
me: NOW this message is encrypted.

Is this actually a limitation of profanity/omemo plugin, or is there some other issue?
