i developed a document management app for SharePoint Online. The app provides an UI where users can upload documents and edit some custom properties. The documents are stored in a document library with custom columns.
I'm currently facing an issue, where the items properties get overridden, when users upload a new version of the document. This behaviour only occurs for Word documents, where the custom columns seem to be mapped to the Word document properties.
Is there a way to stop SharePoint from automatically overriding the item properties with the document properties?
