Update: If I re-save the page, the new lines appear correctly in the textarea. I looked in the database and it appears new lines are stored as actual new lines rather than \n. (Screenshot of database: https://ibb.co/p2hRtMK )
So it looks like the real problem is with the way WP All Import is adding \n rather than a new line. I may need to separate these titles into 6 different fields if there is no way around this. Not an ACF problem after all.
Hi John,
The new lines come from either (a) the textarea custom field in WP admin Edit Page, or (b) added from WPAllImport custom fields (where contacts are imported from a CSV file):

I am not trying to put new lines on a front-end page anywhere. It is the back-end Edit Page where I want them converted to new lines inside the textarea for editing (first screenshot).
Thank you.
