I have an issue when log in cs50 IDE. After I go the site, login with github, cs50 IDE keeps loading with the message "Preparing your environments" but doesn't take me to sandbox with the project I was working on. I've tried to refresh the page, refresh the browser, and restart my computer too, but the issue still stays the same. Btw, I currently use Chrome. Anybody had the same issue or heard about this? Thanks.

Apologies for the trouble! Should be working now. In the future, please report issues to sysadmins@cs50.harvard.edu!


I just wanted to say I got the same issue, although I use FireFox. The problem seems to be on their side.
