I use WAMAP for homework and have it integrated in Canvas. It is set up so that I can set the due dates in Canvas and they are automatically updated in WAMAP. Students only access WAMAP through Canvas. This all works great! 

There is one issue - late passes. WAMAP lets you grant a number of late passes at the beginning of the quarter. There should be a 'Redeem late pass' button when a student tries to access an assignment after the due date, but it does not seem to be showing up consistently. Does anyone have any experience with this?

Thank you!
