I logged into Jira (cloud) today to find the default and all custom create and edit screens completely empty. We have a default screen configuration that is shared between a few projects, but many of our projects have custom screens and screen configurations. All of them are completely empty. There are no fields displayed.
How could this have happened? The audit logs don't show updates to screens. Someone could have gone through each screen and removed all of the fields, but this seems unlikely.
