Good to know it is not just  for me. This morning everything runs fine, BTW.

I don't mind if I have to refresh once in a while, or not gaining points immediately. But doing mastery challenges (to get 100% mastered on math again) is kind of frustrating if exercises are marked as correctly answered, and then not counted as done.
