Cloud subscription Acrobat DC Pro latest update broke something. You can no longer perform most editing functions on GST pdf's such as delete pages.
You can extract. You can print to a pdf. Then you can edit those which is a pita.
Go System Tax uses Itext ? pdf clone engine to create pdfs. (I thought there was a way to select using your own, but no one can find the global setting to change that)
Workaround for now in Adobe : View, Show, Navigation, select Tags.
In the left hand pane, delete the tags.
Then you can edit.
Question: what is an Adobe tag??
