Files App
I finally purchased Filebrowser Pro, and 8player, which fits most of my file transfer needs between my iPhone, iPad and PC's, particularly my media storage device attached to my Netgear router.
About that same time I discovered the new Files app. Could. not. get. it. to. work. Fast forward and one day I'm logged into my router doing some maintenance when I noticed my readyshare folders were lit up like links (they don't do that from a PC) so I select one and hocus pocus it opens my Files App and I log in using my router credentials and eureka I am in and can do anything from ANY app.
Until a couple if weeks ago, that is, now, no matter what I try I cannot get connected.
