When a reservation is locked in Mews (to ensure the guest keeps the specific room they have been assigned), the reservation currently becomes unlocked if the guest updates their check-in time during online check-in (e.g. via Duve).

This creates a risk that the room assignment can be changed afterwards without us noticing, since we do not receive any notification that the reservation was modified and unlocked.

Proposed improvement:
If a reservation is locked, changes made during online check-in (such as check-in time updates) should not automatically unlock the reservation. Alternatively, Mews could keep the reservation locked or automatically re-lock it after the change.
