I have resolved my issue.
I’m not sure what happened. All my progress, including the certification for Responsive Web Design, have now disappeared.
I’m not sure how to get them back (tried to log in from different browsers, different machines, to no avail), It has erased my username, and i know it is still out there, has when i tried to put in it says it is already taken, I’ve always signed in with my email…
Thanks for any help!
