Doesnt work on iPhone 6

My friends who have older devices are still able to use this app (which hasnt had the name changed from Sametime), but Im running the application with the same proxy and port as they are and getting bad results.

It imports new cut group names, but doesnt delete old ones. It disconnects my connection on other devices and shows me as available, but doesnt show any other users as being online and doesnt send me the messages they type.
