Hey Frankk,
Sorry to hear about the trouble you have experienced because of new UI of Adobe Sign.
Our vision for Adobe Document Cloud, which includes Acrobat, our PDF services, and Adobe Sign, is to have a fully integrated location for your document and e-signature processes. We want our customers to have a seamless experience to create, collaborate and share documents - whether its to gather comments, or to have someone e-sign a document, and this meant creating a new online hub for Document Cloud, where all your document-related activities can be managed.
This is a limitation of the new interface and agreements older than July do not appear in the search results. Engineering team is working on it to deliver the fix in near future.
Regards,
Akanchha
