Environment: SharePoint Online (Office 365 hosted, SharePoint 2013) I have experience with older versions of SharePoint, but am new to SP2013 and Office 365.
I am a site owner and Site Collections Administrator with full control. I just added a "Media and Content > Content Editor" web part to my page, added content, and saved it. The content was visible on the page. I then went back in and changed the audience to an Active Directory group that I am not a part of, and after saving it again, it completely disappeared. I would expect the web part not to be visible when simply viewing the page, but I thought it would be visible when I was in "Edit" mode.
As an admin, how do I work with web parts when I am not a member of the audience? By the time our site is fully built, I expect there to be hundreds or more web parts for which I am not part of the audience, but which I will need to edit and maintain.
EDIT: This is reproducible and not limited to the Content Editor web part.
TL;DR - Web Part with audience targeting is not visible to admin even in Edit mode. How to view/edit?
