Subject: Urgent – Unable to Sign In and Access Existing H5P Activities Dear Lumi Support Team, I am experiencing a serious issue with my Lumi Education account. When I try to access Lumi Cloud, I receive the following error: "Unable to sign in. Please try again." The problem occurs on multiple devices. I cannot access the Lumi homepage, my dashboard, or the existing H5P activity editor. My activity link: https://app.lumi.education/run/2WFZig I am concerned about losing my existing educational materials because I have spent considerable time creating interactive learning activities for my students. Could you please help me: 1. Restore access to my Lumi account. 2. Check whether my existing H5P activities are still safely stored on your server. 3. Help me recover access to my existing activities and deployments. 4. Investigate whether this is an authentication or server-side issue. Thank you for your assistance. I hope this issue can be resolved as soon as possible. Best regards,
