Our cloud instance of Jira has had Smart Checklists working for years, and I noticed about a week ago the functionality is broken. The button at the top of the Issue to create a Smart Checklist is there, but when I click it, a blank space opens where it should populate the controls to view/add/change/delete checklist items... but it's just blank. upon doing an inspection of the blank space, there is no HTML w/in the <div> tag.
Anyone else experiencing this?
