RESOLVED: "Uh oh, it looks like we ran into an error. You need to refresh. If this problem persists, tell us." This issue had took me to this page, so here I am reporting an issue. Our internet is technically really bad. But, after submitting my answer in the Mastery Challenge in Missions and shows my answer is correct and immediately it shows the issue quoted above. And this occurs for every single problem! I just refresh though and it correctly identifies my progress and shows the next question. I don't just want to constantly refresh. Please solve my issue as soon as you can, Khan Academy team. I have been a KA Member for over 4 years, and have never seen anything like this. Please contribute to this chat if this situation still is constantly happening.
How can we help?
