If you do any sort of mixed source notes in Logos Notes, with quotes or OL languages, what looks right on the desktop won't necessarily appear correct when it gets opened on your iPad. The sizing stays mixed to some extent. I now do a Ctrl-A to select the text, make the font bigger, and then reduce it to my preferred default size. You have to remember this or come back and do it. This straightens things out.
I am not sure if FL can fix this lack of uniformity. I think there are some underlying coding issues that make this less than a slam dunk. Platforms have their quirks.
