I am having reports of the same issue in my organization. We are using Adobe Pro 2015 Version: 15.6.30499.341880 with Windows version 1703.
Workers are marking the document for redaction, applying the redaction marks, removing the hidden information, then Save the document. After the document is saved, the pages turn white and all that is left are the redaction marks.
Are there any answers from Adobe on this issue????
