I tried to export my manuscript to HTML and then transfer to Word, but the 'export' is just the title of my manuscript in bold font with no other text underneath.
Go to manuscript title page. Go to export tab. Click 'export to HTML'.
Hello there - this is because you moved everything you've written at the same level as you manuscript. Making them notes and not part of your actual manuscript.
Drag and drop them back under the manuscript for them to be part of it.
