POSSIBLE BUG / GLOBAL SETTING ISSUE - changing check in times - impact on cleaners unable to meet unreasonable deadline

Subject: Editing check‑in time for one reservation updates all future guests across all properties

Issue Summary

When I manually change the check‑in time for a single guest reservation, the system automatically updates the displayed check‑in time for all future guests across all properties.

This behavior suggests either:

• a bug where reservation‑level edits propagate globally, or

• a UI issue where a global default is being modified without clear indication.

Steps to Reproduce

1. Open an existing reservation

2. Manually edit the check‑in time for that specific guest

3. Save the change

4. Observe that:

   • The updated check‑in time now appears for all future reservations

   • The change applies across multiple properties, not just the one reservation

Expected Behavior

Editing the check‑in time for a reservation should affect only that reservation.

Account‑level or listing‑level default check‑in times should:

• Be clearly labeled as such

• Never be modified implicitly by editing a single guest’s reservation

Actual Behavior

The edited check‑in time propagates globally, impacting:

• Future guests

• Multiple properties

• Displayed check‑in times used by automated messages, calendars, and cleaning workflows

Operational Impact

This issue has high operational risk, including:

• Incorrect automated guest messaging

• Confusion around arrival times

• Potential cleaning and turnover timing errors

• Loss of trust with guests and cleaners

Because check‑in times are foundational to multiple systems, this behavior is especially concerning.

Additional Notes

• This was not an intentional global change

• The UI did not clearly indicate that a default or global value was being edited

• It is unclear whether the change affected:

  • Account‑level defaults

  • Listing‑level defaults

  • Or both

Clarification and correction are needed to prevent recurrence.

Requested Actions

1. Confirm whether this is a bug or intended behavior

2. Identify which setting was modified (reservation vs listing vs account)

3. Ensure reservation‑level check‑in overrides do not update global defaults

4. Recommend a safe workflow for guest‑specific early/late check‑in adjustments

Thank you — this issue affects core scheduling and messaging workflows, so I appreciate it being reviewed by the appropriate team.
