Can't connect message flow connectors
I have bizagi v220.127.116.11.
I try to use the message flow connectors to model syncron message flow, but it does not work for me.
I create a task, I connect a message flow connector to it and I can't
connect, link it with any task or message type start event. (Nor in the
same, nor in an other swimlane)
Previously it worked for me, because I have these connectors for
previous processes linked perfectly but since I updated bizagi it
Thank you for your help!
