I was going through the Wix Corvid Forum Posts and found a report of a broken Wix Support link.
The working article https://support.wix.com/en/article/about-filtering-and-sorting-database-content-displayed-in-page-elements links to https://support.wix.com/en/article/how-to-filter-a-page-based-on-the-currently-logged-in-user a non-existant URL.
@brett-haralson @sheyla @stevenjose Please pass this along to the relevant department.
