Update - We are continuing to work to fully restore all of our reports (e.g., browsable title list, conflict reports, depositor reports).

We are still processing your deposits. Submission processing is not broken; it is only the missing emails that are an issue. We are working to fix the bug resulting in missing emailed submission logs. As an alternative, you can always use our admin tool to review your recent submissions.
