Hey since I can't find any other place to ask about this app I'll post here.
I downloaded the app yesterday for the android. I tried it yesterday and am getting the same issues today. I start up the game pause it making sure the pipboy app is enabled, then start the app. which sees my xbox one, but it never connects and I get no error unless I don't have the game started.
As I am typing this the app is just stuck on the connecting screen. Now if I turn off the pipboy app in game it will fail after awhile.
For the bethesda people. I am using a Galaxy 4 tablet with android version 4.4.2. Now when I use xbox smart glass app it works fine and I can connect to my xbox.
