I think I'm not being clear. There are 32 chapters. There are 32 sets of sources (input as endnotes), one set of end notes at the end of each chapter. (Every chapter has at least two section breaks, some have more; but those have nothing to do with endnotes.)
Yes, to create a file with multiple chapters, I have to use a section break between chapters.
I am not sure what "suppress end notes" does--is it so that one doesn't have to
view the end notes? Are we trying to trick Word into "thinking" the endnotes aren't there?
I can't imagine why I would want to "suppress" any of the 32 sets of endnotes.
Now for the mysterious "suppress endnotes" function.
The path in Word for Mac 365 (v 16.29.1) is:
File > Page Setup > select Microsoft Word, Whole Document, Margins tab. Then one can see the box for "Suppress endnotes." IT IS GRAYED OUT.
Come on, Microsoft. Surely one of your legion can weigh in about why the box is grayed out.
