My TiVo Android App suddenly stopped working on my Samsung Galaxy View (Android 5.1.1). I am getting a "Network Error" and cannot get past the initial sign-in screen. I have gone so far as to do a factory reset and have tried to install earlier TiVo versions to no avail - same result. TiVo customer support was amiable, but not helpful. My DVR is a Roamio Pro. The app is working on all other devices. Does anyone have a solution/suggestions? Thanks.
