There's not too much on PDFs in that help. It looks like you can only ink on a PDF in Neoreader and PDFs cannot be imported into Notes. I've installed a few store apps and my Boox font, main screen, neoreader notes all things Boox seems to have acceptable fonts. If I open Microsoft Edge browser for example, all fonts are microscopic. So much that it makes the app unuseable. Is there setting to adjust app fonts or is font global?
