Directv Streaming with Apple TV problem?

I stream Directv with Apple TV and ATT fiber internet. When the app is first downloaded it works fine. I turn the tv off, turn it on again and the app home page will not let me navigate to the left side menu that contains the search, on-demand, etc. I delet the app, reload it and the sequences starts all over. I've call Directv support 3 times, and still the problem persists. Any suggestions?
