- If students were used to using WeBWorK before the LTI link, they may be used to navigating between assignments within WeBWorK, which could be at play. I don't have a system with LTI grade pass back enabled to play with, but I vaguely recall the links to LTI-linked assignments being greyed out for students on the main assignments page. Can someone verify if this is the case?
- If for some reason Blackboard is not setting the grade pass back URL properly for these students, then they would see this same behaviour.
I don't see a good resolution to this until we're able to corroborate whether this is a system issue or a student issue.
