Hi @cl.nam

We could reproduce this issue at our end. It’s been logged in our internal issue tracking system with ID VIEWERAPP-222. As there’s any update, you’ll be notified.


The file that you’re trying to upload does not represent MPX file format. Due to Description of the MPX Project File Exchange Format the MPX is ASCII file format but the attached file is binary so it can’t be opened.
