Hello again,
So I have been doing some digging, and I can see:
when gone_secure is called, I have context->msgstate equal to
OTRL_MSGSTATE_ENCRYPTED
Just before, "otrl_message_sending", msgstate is still equal to
OTRL_MSGSTATE_ENCRYPTED for the appropriate contact.
However, during the call, I have a message event triggered, and I can see
the message "OTRL_MSGEVENT_ENCRYPTION_REQUIRED".
And the value of context->msgstate changed to OTRL_MSGSTATE_PLAINTEXT
After the end of the call of "otrl_message_sending" the msgstate is equal
to OTRL_MSGSTATE_PLAINTEXT.
Maybe that would help to identify my mistake?
Thanks
Kind regards
Pierre
