Completed lessons not showing up on my end.
Hello! I've had this random issue off and on all year -- sometimes a handful of students will complete a set of lessons and it won't show up on my dashboard at all. I assign them a grade of "0" in the school grade book. They will immediately come to me and show me (on their phones) that the lessons were actually completed. Why does this keep happening? Is there something I can do for this to NOT continue happening?
