So Plex is claiming that their most recent updates to the iOS app will no longer support PlexPHT, which basically makes the Plex iOS app useless for controlling playback to the RasPlex.
Since PHT will no longer be supported are there any plans to make a PMP version or anything that would resolve the issues ?
This really needs to be addressed and sooner than later. The functionality was perfect on 4.1 - so what has changed to break it can surely be changed back - at least until proper support or integration with PMP to use iOS devices as a remote. It is literally useless now. 
There are PMP versions for the rPi now, but it wouldn’t be supported by Rasplex. OpenPHT 1.7 is supposed to work better with the iOS app, but I haven’t tested it yet.
