Hello Lumi, I am a LUMI user, along with several of my fellow teachers. We are currently working on a project to create interactive learning materials using LUMI. However, for the past few days, we have been encountering several issues: image uploads stall at 100% without actually completing, navigation buttons have disappeared, audio uploads are failing, drag-and-drop settings are malfunctioning, errors occur while creating games, and so on. We would appreciate your attention to this matter and a solution. Thank you.
