Im ready to throw my phone

I cannot sign in using my xbox account. It wont give me an option. I sign in on my comp just fine. I use the same username and password for the app and it says its wrong. I understand why developers want to use all kinds of media. But when I pay $70 for a game. I expect everything to be on that console. Not spending hours on stupid crap like this. I it works for you great. But I cant find out why it wont work for me.
