The Screen flow is launched from quick actions on the contact record page. The flow is re-executing/ launched every time when the browser back button is clicked or trying to go back.
So the conditions/ decisions added will be executed again. Example :- on the verbal Commitment Status check decision for checkconditionvalidation and goes through the next decision and exits. works flawlessly, no issue works as designed/ excepted. But when the browser navigation buttons is clicked then the flow is running. For some of the Screen elements i have added an LWC toast message.
