Have had this set up working for 3+ years. Slingbox Pro HD, Slingbox iOS app on iPhone and iPad. Both running latest version of iOS (9.2 I think). Last time I used either (about a month ago) everything worked fine. I could access my DirecTV Menu and view recorded content from DVR with no problems.
Last night I tried both and neither app will access the DirecTV Menu or Guide!??
Could the latest iOS update have broken it?
