Why could I only do one or two tasks before it went into review?
Some of our tasks are only available in limited numbers at any one time, with new tasks being added in small numbers. Even though you might have a maximum number of tasks allowed, they may not all be available at any one time. This is especially true for Review tasks, which need to wait for 'Source' tasks to be reviewed.
With a lot of Fives eligible for our tasks, it can lead to some stop-and-start tasking. We've been working on ways to make those limited tasks less annoying, or at least give some warning about the limited numbers.
