After opening the online program and a file, the program and file both close without notice losing any edits not saved. I entered a ticket for HELP. They were not able to help me. They have no idea why this happens. I launched the online program using both Chrome and Microsoft Edge. Problem happened with both every time. I timed it once and it lasted 34 minutes. Other times it seemed like only 5 -10 minutes. Does anyone have similar problem? Any suggestions?
