# Scheduler booking and Gmail message filter fixes

Source: https://developer.nylas.com/docs/changelogs/2026-09-18-scheduler-booking-and-gmail-filter-fixes/

## Fixed

- **Cancelling a booking with a Notetaker** now works end to end. Previously, when a booking's event had a Notetaker attached, cancelling it returned a success response but the booking stayed active, no [`booking.cancelled`](/docs/reference/notifications/scheduler/booking-cancelled/) webhook fired, and no cancellation emails went out.
- **Rebooking a slot after the event was deleted on the calendar** now succeeds. Previously, if a booked event was deleted directly in Google Calendar or Outlook instead of cancelled through Scheduler, availability showed the slot as free but booking it returned `400 The selected timeslot is unavailable`.
- **`any_email`, `from`, `to`, `cc`, and `bcc` filters** on [`GET /v3/grants/{grant_id}/messages`](/docs/reference/api/messages/get-messages/) now match Gmail addresses case-insensitively, consistent with other providers.
