January 14, 2020, update for SharePoint Enterprise Server 2016 (KB4484215)

• You are unable to access Office Add-Ins from a document that is opened in a browser when they are provided by the SharePoint App Catalog Service.
• When you log into SharePoint by using multiple authentication types at the same time such as a SAML token and a FedAuth cookie, the URL redirection happens to the root of the web application instead of the actual resource.
• Fixes an issue in the SharePoint eDiscovery Center portal where errors are produced when you export content from a site preservation hold library.
• When you create a new document in Word and try to save it to a document library with a content type that has required properties, you are blocked from saving because the Document Information Panel doesn't show required properties.
• Calendar overlay items that are listed under Calendars in View are not clickable.

• Fixes performance problems when you perform actions such as connecting Project to the server, trying to see a list of projects from the server, going to the Project Center page and so on.
• When the Schedule Variance Percentage (SVP) or Cost Variance Percentage (CVP) earned value becomes very large, this causes an overflow condition. It causes the client-side object model (CSOM) or REST calls to fail when you access the project. The SVP and CVP values now have a lower limit of "-100%" and upper limit of "100%".
