My assignments pages are not working properly. I logged in this morning and no scores are listed, as though I've never assigned anything, and it also won't let me assign new lessons. (See pics) 

1. I have been using Khan Academy with my homeschooled kids since September 2020 and there is usually a long list of scores here. This morning it was blank for both kids.

2. When I try to assign new lessons, there is no name listed and it says I have no students on my list.  However, my kids are still listed on Dashboard, just not on the drop down menu when I'm trying to assign the lesson.  Therefore, the "Assign" button stays gray and won't let me click on it.
