Directv app on mobile receiver detected - DirecTV

No receiver or dvr detected
I recently installed the Directv app on my Samsung phone and tablet. After many attempts trying to get to detect my HR44 receiver and DVD, uninstalling and reinstalling the app, it finally detected the receiver one time. I was able to register the DVR. There must be a problem with this app because it has not connected to the receiver/dvr again and will not show the programs recorded on the dvr for download to my phone. Phone conversation with customer service could not resolve problem. I would like to hear from others to find out how wide spread this problem is. For now I have given up trying to get it to work as advertised and assume the app still has a lot of bugs to be worked out.

This question, "Directv app on mobile receiver detected," is about DirecTV channels, programming, equipment, and sports.
