as of jan. 7th 2020, i've been doing maths for at least 30 minutes from around 5:50 to 6:20 PM (central standard time), and for some reason, no matter how many times i reload the page and click the "today" tab in the dropdown menu, (as my time on khan academy yesterday was around 97 minutes, and those logged just fine), it's just telling me that i've done zero minutes of math. i don't know why this is happening, and think it might be some kind of bug or something.
i don't know if it helps to know this, but i've had khan open since yesterday on my computer because it's easier to remind myself to do it for a bit every day, but i don't think that could be causing any issues like that. any ideas on how to fix it? i'm supposed to turn in time on khan as an assignment, and i don't think my supervisor would believe me when i say it's a glitch.
