I have a Behance profile of long-standing as ChrisARaymond, and multiple projects, all connected to a gmail address. Now I cannot access it because my Adobe ID is connected to a different email address. I get an endless loop as Behance refuses to let me sign in with my old credentials, and when I sign in via AdobeID, my profile and projects are empty.
Did your programmers think through what you were doing before you implemented this? It's beyond ridiculous.
