Are you sure that the flow/activity that you try to debug is already deployed to that environment?
Can you debug on other flows/activities?
Hi Lavanya R,
I already had the same issue. Have you already tried to rerun the app, then disconnect and connect again the debugger and enable the breakpoint?
Hi, If you stop the application with the red button and then run it again, it should work. I had the same problem like an hour ago. Hope it works :)
I am also having the same issue, is this ever resolved for you?
