Changed our email recently, request for signature page only shows loading and never fully loads now

We recently went through a branding change so we changed the email and Sender name associated with our Adobe Sign account. I can login with new email just fine, however, I don't see any of our past completed documents and when I try to send a request for signature, the page gets stuck on loading and I never even get to the page to load the document for signature. Chat says they are closed, and the endless menu on the phone gets me no help at all.
