No. Changes to the auto-approval cutoff time do not apply to updates that are already pending.
Each update captures the auto-approval settings (including cutoff time) that were active at the time it was submitted. If an admin later changes the cutoff time, the new setting wil apply only to updates submitted after the change, not to those already waiting for approval.
This ensures fairness and predictability for staff submissions while allowing admins to update approval rules for future activities.
