With the new iCloud Drive app in iOS 9 I've decided to start making more use of iCloud Drive. I found the post about the "External Files" command in the Reader, which I had been unaware of. This is a really great feature, and I have put a lot of my Chinese texts on iCloud Drive to that I can access them from within Pleco. However, when I tried opening a file, even a quite small file, it seemed to take a very long time to open. A 2k file took about a minute and a half to open. Perhaps this is due to congestion on the iCloud server or on the net generally. But when I try to open a small file in the iCloud Drive app on my iPad it opens almost immediately. So it seems to be a Pleco issue. Could this be an iOS 9 issue? I've never tried this on iOS 8, as I just discovered the feature today, and I've already to OS 9.
