After loading a saved view on the Team Board, when clicking the next or previous arrows on the Timeboxes, it does not load the next or previous timebox, it jumps to Unscheduled or all the way to the first or last timebox.
This only happens when using a saved view.
Saved view may have become corrupt, even if no error is shown.
Have a user access the saved view, make a small change such as changing the width of a column or switching the order of two columns and save the saved view again. Then have the user select Clear View, load the newly saved view. The next/previous arrows should now work correctly.
