And that problem should now be fixed. The main issue was that when it was not loading all the Google fonts, it was failing to load Noto Sans. I did not notice this on my PC or on Android, which both had Noto Sans installed, but I did on the iPad, which didn't have it installed. The problem was that I had changed part of the code to use defaultserif and defaultsans to specify a different default for serif and sans, but I was still using the keyword default in other parts of the code.
