OMEMO can only be activated sucessfully if the "Get device keys" button got pressed. Before that i can seemingly activate OMEMO and send messages (i.e. they show up in the conversation view and i got the "OMEMO encryption enabled" status message), but they silently get swallowed and never show up on the other end.
With the OMEMO checkbox unticked i can get successful delivery (of unencrypted messages).
