I am trying to upload a file into the question library and keep getting an error
The upload didn't complete because your network connection was interrupted. When you're ready, try again
From the content of the error message, I would first check your internet speed to see if it could really be related to connection issues. If that is not the case, I was about to advise you to open a ticket with our Admin Support for further investigation. But I can see you have already done so.
I hope this gets fixed soon.
