Just a quick post to let you know that version 2.0 of the Vodafone TV app for Android is now available from Google Play. Requires Android v4.4 and above.
This new version resolves the issues you told us about accessing the App on a device, so please ensure you update to the latest version, especially if you're using Android Oreo.
I still can not get this to open on my Android Tablet and Android Box says device is not supported.
Both are running Android 6.0.1
