Request e-signature services are temporarily unavailable. Some documents and information may be miss

Following up on this.  I first attempted to restart, log out of Adobe, change my Adobe password, and installed an update this morning.  This did no fix the problem.  I contacted the support through the chat <https://helpx.adobe.com/contact.html?rghtup=autoOpen>

And once I reached a human, he was able to help.  I let him have access to my computer, and he had to go in and remove some files in Credential Manager.  Once we did that, when I opened Adobe, it appeared slightly different than the previous version when requesting signatures, but mostly the same.  The important part was, that it worked!  I am not sure what the problem was, but perhaps the update didn't "take" because those credential files were still there.  In any case, it is working now.
