Known issues we've tracked

Notebooks-in-Gemini integration shipped April 2026: Google merged the NotebookLM workflow into the Gemini app under a new 'Notebooks' surface that cross-syncs with notebooklm.google.com. If you live in Gemini, you can now build and query source-grounded notebooks without leaving the app -- same source ingestion, same Audio Overviews, shared library across both surfaces
2026-04•blog.google: Notebooks in Gemini and NotebookLM, Google Workspace Updates
EPUB file support added in Q1-Q2 2026 alongside the prior PDF / DOCX / Google Docs / web-URL ingestion paths -- ebooks finally drop in cleanly. Useful if you're synthesizing across long-form non-fiction without first ripping epubs to text
2026-04•Google Workspace Updates
Cinematic Video Overviews (2026-Q2 rollout) extends the 'two-AI-hosts-discussing-your-source' Audio Overview format to a video format -- generated visuals, on-screen citations, and the same banter cadence. Treat as a beta-quality feature, but the UX upgrade for visual learners is real
2026-04•blog.google
Education Plus tier (and Teaching & Learning add-on) got expanded NotebookLM limits in 2026-04 -- higher per-notebook source caps and audio-generation quotas than the standalone free tier. The 'restrictive 50-source limit' caveat applies to free-tier users only; institutional Workspace customers should reference the Education Plus quota sheet

Audio Overview generation sometimes fails silently on longer documents, requiring the user to retry

Source parsing can struggle with complex PDF layouts -- tables and multi-column formats often get garbled
