I am using PRPC V7.1.8 and trying to run a post processing activity from the action tab of the flow action. I am aware that you need to click the Post Action on Click Away?check box on the Assignment shape properties panel
However on my screen flow the assignment shape only shows
Enable link if using breadcrumb trail
Only going back
Perform post-processing when navigating back
I am not able to find the Post Action on Click Away? option.
