redirectDelay from postSignOption is not working properly

Hi. We have been creating Agreements using have the following structure:

{
    "fileInfos": [{
        "transientDocumentId": "<<transientDocumentId>>"
    }],
    "name": "<<name>>",
    "participantSetsInfo": [{
        "memberInfos": [{
            "email": "<<email1>>"
        }],
        "order": 1,
        "role": "SIGNER",
        "name": "<<name1>>"
    }, {
        "memberInfos": [{
            "email": "<<email2>>"
        }],
        "order": 2,
        "role": "SIGNER",
        "name": "<<name2>>"
    }],
    "signatureType": "ESIGN",
    "state": "IN_PROCESS",
    "emailOption": {
        "sendOptions": {
            "completionEmails": "NONE"
        }
    },
    "postSignOption": {
        "redirectUrl": "<<URL>>",
        "redirectDelay": 0
    }
}

Note the redirectDelay with value 0. Until a few hours ago this type of Agreements were working pretty good but suddenly for some reason after a signer signs a document it displays the native page of Adobe Sign post signature and thus not respecting the redirectDelay value in 0. The expected behavior (and how this used to work before) is after the document is signed it is automatically redirected to "<<URL>>" (due the value 0).

In fact, after the first group of signer signs the document it get redirected to "<<URL>>" after 5 seconds (I don't know why 5 seconds) but when the second and last group of signer signs the document it doesn't redirect at all and it stays in Adobe Sign page.

Any idea? Thanks in advance.
