Pdf expert signature doesn´t allow to get fields


When we try to get the fields of a document signed in pdf expert 5 on ios (https://readdle.com/products/pdfexpert5/) is not working. But if the document is signed in abode acrobat it works since you have fixed it for version 9.

This is the code that we are trying:

string path = upload.PostedFile.FileName;
Document doc = new Document(path);
Aspose.Pdf.License licence = new Aspose.Pdf.License();
Aspose.Pdf.InteractiveFeatures.Forms.Field[] _formFields = null;
_formFields = doc.Form.Fields;//Raise Error
TextBoxField txtName = doc.Form[“txtNamePru1”] as TextBoxField;
SignatureField signature = doc.Form[“SignaturePru”] as SignatureField;
string textName = txtName.Value;
string firm = signature.Signature.Authority;

Please find attached pdfs signed in both pdf expert and adobe acrobat then you can see the difference.

Thanks for your support and awesome product.
