Hello,
This applies to Microsoft Word for Mac version 16.63.
Applying ‘Tracked Changes’ to a document leads to skipping line numbers in the document, despite there being no additional paragraphs/lines in between pages (see screenshots):
To my knowledge, there is still no real solution to this. This issue recently posed a problem for me, as I needed to number my lines accurately for a research paper and the reader can be easily confused due to the skipping in numbers.
