iOS 9.3.2 on a 6S and have an SD Card Reader that I just bought (like say, an hour ago). Get home, take SDXC card from my Canon Rebel T5i, plug it in, see "Import" icon for like, 2 seconds, then poof, it's gone. Have restarted multiple times, won't work. SD card reads on every other device (Desktop, laptop w/USB Adapter). Per store.apple.com the adapter works for iPhone. Don't have an iPad to try there, so wtf is going on? Anyone know how to fix? Edit -- after force quitting Photos app I can relaunch and get "Import" to show up again but it disappears after. Could it be sheer # of photos that's crashing it? There's a few hundred.
