I use SharePoint 2013!
When I try to edit the reply in the discussion list in community page,I am able to edit and save it. Whereas, when I edit the reply and cancel it without saving it, I am not able to edit the reply again (i.e : even if I click the edit option from the dropdown box,it does not allow me to edit. But when I refresh the page and try to edit again, it allows me to edit.)
Could anyone please try to answer my question.
