I loaded the free version of sling player on my iPhone 6 and all I get is a black screen. The top half is a dark gray, the bottom half is totally black. I never get an option to log into my slingbox or anything. Just a black screen. I have uninstalled the app and re-installed. Re-booted the phone. I have plenty of memory. I can sign into my slingbox from a PC and my iPad. Not the iPhone. I am still running iOS 8.0. I have not upgraded that. Anyone else run into this? Thanks in advance.
