Why are the successors not scheduling?

Successors are Tasks set to take place after another Task. There are a few reasons why your successor may not be rescheduling following a change to a predecessor Task:

1. The successor is Done, meaning that the Task dates have been actualised. No date changes can be made to Done tasks.

2. The successor is Promised and you are not the Task Owner, Assignee or Admin.

3. The task you moved is Planned, and the successor is Promised.
