I've recently upgraded from TFS 2015 RC to TFS 2015 RTM and all seemed to go well... until I went to the Backlog and clicked on the current iteration - all the backlog items in the Backlog tab don't display but they do in the Kanban board - and the same happens when you click on the Capacity tab - it shows a blank screen.
Does anyone know if the upgrade could have caused this?
FYI I had customised the Agile Project Management heirarchy in the RC version to have 4 levels (User Story > Feature > Initiative> Goal) - would this have had any effect?
