So i am having the same issue as is detailed on this bug report CONFCLOUD-68979 However the workaround does not work for me. Unless I'm misunderstanding something.
So I tried the following
1. Create an attachment table
2. attach the file on the page I wanted the word macro
3. add word macro, use the current page (With the attached file)
4. Select the correct file
5. Nothing happens, no preview, cannot insert the file.
Does anyone know if I am doing it wrong or has the bug "gotten worse"?
Thanks for your time!
