My project, that I named email-login, won’t load at all in the editor. I don’t know exactly why, but all it does is instantly redirects me to the last thing I did while I was on glitch. (which is the email-login, obviously) The testing site I made though, when I named it I hard refreshed at the same time which brought me to the same project but just with a different name. I did not notice until I ran the code, which then brought up that “Project not found” thing.
You should contact email@example.com and ask for a hard refresh of the project.
