    Hello Jakgrid Rungsangjun,

    Edits in PDF Reader are saved automatically. When you are using comments, please make sure you have typed in messages in the comment boxes and hit "OK" before making other options. A blank comment box (a box that doesn't have any content typed in) will not be saved even when you hit "OK." Please let us me know this helps. Thank you.

    This does not show how to add voice notes as annotations to a PDF. Can't find any information anywhere ...

    Hello Gerhard van Huyssteen,

    We don't currently support audio annotation for Windows.

    However, it's been added to our future update plan. Please stay tuned!
