I setup a simple advanced taksflow in my org . Hard coded input field to 1 and saved and published the taskflow. Then, changed the input field to 0 and saved it. Then, closed and opened the taksflow and looked at the
taskflow properties. Found that the status had changed from published to outdated.
Based on this testing, as far as I can say, you will need to republish the taskflow in order to execute it using the latest input value.
Hope this helps.
Thank you Mohammad! Yes, that helps - thank you for testing for me.
