I don't have a solution for you, but I can confirm that the app is working on my Android tablet (Lenovo TAB M10 Plus). I initially got a notice that my sign-in credentials had expired, but after signing back in I was able to access the content on my Roamio Pro.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.
