Hi, a weird thing happened.

I had an assignment yesterday but something weird happened, I choose the answers and submitted and then it said i got the questions wrong. for example: one of my questions had 4 answers and I selected the correct one but after my submission it shows that I got it wrong and it happened to me with 4 other questions. I even contacted my teacher and checked the book and they were correct I selected them but Microsoft teams automatically choose another answer as I started scrolling. my teacher even told me that it is a common problem with all the students that usually happens.
