Pega Eform not working as expected in v26.1.1

Hi ,

I am trying to generate a pdf using Eforms in Pega. The pdf is getting generated using OOTB activity CreatePDF/GenerateEForm but the resulting pdf is still editable. I have tried to use the flag pyPerformFormFieldFlattening and set to true but it is not working. I have also used the workaround to copy pyEform data to pyEForms(1) and then use concatenateEForm with PerformFieldFlatenningFlag but it is still not working.

Pega mentioned that they have fixed this in v26.1.1 but it is still not working. Any help would be appreciated.
