I've noticed over the weeks of testing the various iOS 10 Public Betas that Emby is not a happy camper. Playback works so-so but the browsing of folders and files is impossible with crashes and sticks at loading most of the time.
Trying not to complain. Just trying to inform! =)
iOS 10 final should drop to the public by early September so you guys have about a month to figure it out before your flooded by the angry mob.
