Ok here goes:
Running Plex Server Version 1.2.7.2987
Files are mix of .M4V and .MP4
They play back fine on browser (Chrome), on Android devices, on Roku
However most are not playing back at all on any of my iOS devices (ver 4.5 on iOS 10)
Any ideas? I have deleted and removed apps, uninstalled and reinstalled server etc. to no avail. Again playback works fin on everything except iOS.
