NotebookLM customers may have experienced an issue where all premium account tiers are being incorrectly downgraded to free.
\*\*Description\*\*
The issue with NotebookLM has been resolved for all affected users as of Tuesday, 2026-05-19 21:04 PDT.
From preliminary analysis, the issue was triggered by a recent software update resulting in accounts on premium plans being incorrectly recognized as free accounts.
The issue was mitigated by restoring the system to a previous stable state, which successfully reinstated the appropriate service tiers for all affected accounts.
We thank you for your patience while we worked on resolving the issue.
