I am a student. The semester started and every class is registered and posted. I can see the assignments in the calendar on the phone but not on the computer. The color of classes is grey and when I change the color of class, it doesn't be applied and stays in grey. On the mobile phone, I can see the classes in different colors. But on the computer, there are no classes on the calendar. It worked until last semester properly which is 2 months ago and now doesn't work. please help!
