Greetings! I would like to ask for your help. I can't upload my works to my classes. It says, "Couldn't attach file. Try again." I tried waiting for a day to see if there's a difference and because I thought my wifi was slow but still, it doesn't work. I even tried using my laptop to upload my files and it just told me that the server was rejecting it. Please fix this or do something. Thank you.
