I ran into a similar problem, and it was tasks assigned to multiple
individuals. When a task is assigned to multiple people, the
"assignedToID" is the first person listed. It doesn't care about person
2, 3, 4, etc. only the "primary assignee". I switched my reports to
"Assignment Users ID", and that pulled all tasks a person was assigned
to regardless of whether they were first, second, etc.Something worth
checking.
