We are testing the mobile functionality of Absorb and came across an interesting problem with the navigation arrows. Upon completing a course and submitting an evaluation, the only arrow at the bottom that is in dark purple is the back arrow. That signals back is the only option for a user. After submitting a course evaluation, the up arrows should also be in dark purple to intuitively signal how to exit the course.
Having the up arrows grayed out signals to a user that the functionality is not available. Especially as they are the same gray color as the forward arrow, which is not available.
