Update: The platform update has been successful. You can now copy/paste images into forum and blog posts.
Currently pasting images into forum or blog posts does not work. This issue will be resolved when an upgrade of our platform will be performed on April 9, 2026.
Meanwhile, as a workaround, you can use the Insert Photos option in the editor, or drag and drop the image or file into the uploader.

Thank you @Mike_Walkuski for identifying this issue. We will post an update here when this is resolved.
We appreciate your patience,
Your Hyland Community Managers Team
