Cursive (hand-writing-styled fonts in general) does not work on mobile Safari (both the iPhone and iPad).
I have imported Patrick-Hand font from Google font and it displays well on my laptop; however, it is replaced by a different font on my iPad.
I tried different hand-writing-styled fonts, but all of them were replaced by this same (default) font on my mobile devices.
This is what looks like on my laptop (what I intended).
This is what looks like on my iPad (and my phone as well, which I did not intend).
I imported this exact same font to other note-taking apps or platforms for experimental purposes, and there was no such issue.
