My bank just emailed me something called a PDF and on my phone I have no idea what that means or whether I can even read it. What is a PDF supposed to be?
had the same thing last month with a bank email. a pdf is just a document file that keeps the same look on any device so you can read it like a paper page. on your phone tap the thing they attached and your email app should open it. tbh i use them for the planners i sell too.
