I like to read PDF files on my iPhone. I usually store them in iCloud Drive, so I can read them on any device. The PDF files look great on MacBook Pro and iPad, but I often have to squeeze to zoom to resize the text on my iPhone. Unfortunately, this forces me to scroll horizontally from sentence to sentence. How do I resize text in a PDF file without having to scroll horizontally on an iPhone? The code responsible for reading a PDF file should allow recovery as a browser does (configuring display port), but this does not seem to be the case.
