I have the Windows Phone App (the Metro one for Windows 8.1) installed, but when I plug in my phone (unlocked HTC 8x running GDR3) all it shows is the phone's name, phone number, and battery life. I can't see the storage usage, pictures, or music as the Metro app's store page promises. I'm thinking that this may be because the Metro app was never updated for GDR3. Does anyone else have this problem?
EDIT: Since updating to Windows Phone 8.1 this is no longer a problem.
