I mistakenly clicked on "Hide Grades" when I meant to change my grade posting policy, thinking it was the same thing, even though I have used the grade posting policy correctly in the past. I had an embarrassing and potentially disastrous moment when a student wrote back about comments that were intended only for me, not for the student. I am lucky that it's a student I like, and that I worded everything as positively as possible. But it should never have happened.
I called the help line, and the agent said that he has heard this complaint before. I don't really understand the purpose of hiding grades that have already been posted for students to see, and I'm not sure the agent did, either, but I assume it's useful to someone for something. I suggested that "Hide Grades" needs to be reworded to "Hide grades already posted," but I'm not even certain that that's appropriate. Please find some way of making clear that students can see grades posted even while "Hide Grades" is selected.
