my partner complains a lot as she cannot receive my messages except that
one message appear:
"...sent you a message that was intended for another session. If you are
logged in multiple times another session may have received this message"
also I cannot receive her messages.
restarting Jitsi helps (sometimes)
I have opened a ticket some time ago - any chance that this issue will
be fixed in medium time range (I cannot provide patches, sorry...)
