Send project folder link to new coordinator immediately

Coordinator changes can leave project folders unshared and block photo uploads. Notifying the new coordinator with the folder link gets uploads started and closes handoff within minutes.

Overview

When coordinators change, shared drives often remain inaccessible and photo delivery stalls; that creates slow handoffs and rework. This flow emails the new coordinator the folder link and updates the checklist record so uploads begin within minutes and handoffs close faster.
