-Sorry, I forgot to mention I already tried Status Bar option, and page number is already ticked. When I untick and tick, it doesn't fix the problem.
-In Word 2019 Draft view, if I create or save to the default word doc file, there are no page breaks shown when I insert page break eg using Ctrl-Enter. They are there but invisible.
However my old 1997-2003 docs still show page breaks, so I avoid using 2019 format.
