**Description:**
We are experiencing an issue with AudioOverview, VideoOverview, NAPPS (Notebook Apps) for NotebookLM users, beginning on Thursday, 2025-09-11 10:04 PDT.
Mitigation work is currently underway by our engineering team.
We do not have a full mitigation ETA at this time.
We will provide an update by Thursday, 2025-09-11 15:00 PDT with current details.
**Symptoms:**
NotebookLM users may see failures to generate:
- Audio Overviews
- Video Overviews
- Reports
- Flashcards
- Quizzes
Features launched earlier this week have been rolled back for now.
(Quizzes, Flashcards, Reports) (https://blog.google/technology/google-labs/notebooklm-student-features/)
Any previously generated artifacts are accessible. All other features and CUJs are believed to be working. E.g. text Q&A chat, adding sources should work
**Workaround:**
None at this time.
