On the last day of a Sprint our team have noticed the colour change from Blue to Grey when the sprint day has not completed. The colour actually goes back to grey rather than green, so it’s like the sprint didn’t start at all. This confuses the team as when Blue the current Sprint list is highlighted being a different Colour. Ideally an option or change is needed so that this remains blue until the day has completed. So I imagine this would be a custom change to the time of the timeline when the Sprint completes.
