Hello Augusts,
As per the description above, you are not able to edit the PDF file, Is that correct?
I have checked the record and found that you are subscribed to Adobe ExportPDF service on your current Adobe ID, using the Adobe ExportPDF service, you can easily turn PDF files into editable Word, Excel, PowerPoint, and RTF (Rich Text Format) documents but you cannot edit PDF files with Adobe Export PDF. You need Acrobat DC to edit PDF files. See Adobe Acrobat Pro DC: PDF converter, convert PDFs from anywhere.
By default, Adobe Reader or Acrobat DC runs in protected mode to provide an added layer of security. In protected mode, malicious PDF documents can’t launch arbitrary executable files or write to system directories or the Windows Registry. To check the status of protected mode, choose File > Properties > Advanced > Protected Mode. For more information, you may refer to Protected View feature for PDFs (Windows), Adobe Reader
For troubleshooting related to Adobe ExportPDF service, you can refer to Troubleshooting Create PDF, Export PDF, Adobe Send, Fill & Sign … services(PDFPack or Document Cloud Services).
Let us know how it goes, and feel free to update this discussion in case you need further assistance.
Regards,
Anand Sri.
