So, whenever there is an update, i tend to mess around with my ph a bit more than on the regular. Yesterday after I did the update, i noticed that I can now attach a document when responding or forwarding an email (I had to save it in my could drive first which is no hassle at all). I was curious whether this was enabled long ago and because I gave up so long ago, Ive missed the boat all this time. Either way, i'm thankful for ios10 inspiring me to mess around with my phone even if it wasn't from ios10. Thanks ios10!
