One of the answers in this ticket mention merging several SurveyJSONs manually as a workaround to exporting multiple submissions into one PDF. Unfortunately, it seems the link has died or I just don't have access to it. This was the link that was given: https://surveyjs.answerdesk.io/ticket/details/t3449
I have the same problem which is why I'm hoping to see the answer in that link. Can we reiterate the answer here?
