There are some activities which I need to cancel. I'm not able to cancel them manually since whenever I click Perform->CancelIed->OK, just page is refreshed and nothing happens or processing data modal never ends.I tried to cancel them using web service but while some of them are cancelled the rest stuck on open status. Also tried below solution but didn't work.
Is there anyone facing this issue too? The workflow is below. I could complete the current node and close the activity but what I need is cancelling.
