There seems to be a bug when clicking on the PDF button for a Quote with custom Footer. The resulting PDF is missing the line breaks in the Footer (i.e. the Footer appears as one single paragraph rather than two or three separate paragraphs).
Have you tried inserting line breaks using - br between < > ?
I think @AJD is trying to point out you need to add <br> for line breaks.
eg.
hello, greetings<br>Qwerty, welcome
will give you
hello, greetings
Qwerty, welcome
OK, adding the <br> coding worked, although it’s a bit of a nuisance - why do we have to do this for Quote footers but not for Invoice footers?
I also found a “workaround” by clicking on Print and then printing to PDF. (Rather than clicking the PDF button.)
