‌Document path not valid, since the update, when using in-person signing for the second signer.  It is valid, because it worked for the first signer.  I have restarted the iPad and it will work once, and then the next document will give me the same error.  Since the update, it takes 5 minutes to think about loading the document for the second signer, if it loads at all.  Please help!
