- In Calendar settings, Use for availability calendars are read to block conflicting times from booking availability.
- Write bookings here controls where Cyntree writes event updates for booking create, reschedule, and cancellation actions. Only one calendar across all connected accounts can be the write target.
- Show in Cyntree calendar controls display visibility inside Cyntree calendar views, separate from availability blocking behavior.
- Send bookings to calendar is the business level booking sync toggle. If it is off, bookings will not be written to the external calendar even if calendars remain connected.
- Remote/online services can get Google Meet or Microsoft Teams links from the selected write target calendar.
- External calendar edits are not a replacement for Cyntree booking actions. Manage booking changes in Cyntree first to keep records consistent.
- If sync jobs are pending, use Run sync queue now; if historical upcoming bookings were created before sync setup, use Backfill existing bookings.
- Do not treat calendar connection as instant conflict repair. Always verify active connection status, active calendar toggles, availability selections, and selected write target after account token refreshes.
- Troubleshooting order: booking record status, then calendar settings for availability and write target, then sync queue status.
