When I run the TV control app on my Samsung Galaxy Tab (Android 8.1 tablet) the following error message appears:
The login page could not be reached. Check your connection and try reloading the page.
My device is connected to WiFi (all other apps connect) and on the same network as the TiVo V6 box.
I have the latest version of the app installed and I've cleared the cache and uninstalled/reinstalled.
The TV Go app works fine on the same device.
