Getting comfortable
Looks like it's Android version 9, which seems to be a few years old. Annoying that as the TV is only about a year old.Anyway, TV browsers are awful about not getting updated, so they have all kinds of unexpected problems. If you already own the BI android app, that may work better, but again there may be unexpected issues due to running an ancient version of Android.
Haven't got a copy of the Android app as I'm an iOS person generally.
I just tried Screen Mirroring from my iOS phone to the TV and I think that's probably the best for easy navigation as you don't have to use the remote and control the cursor with the d-pad on the remote, which is awful. Tapping and swiping on the phone is a lot better.
Probably not as great video quality as using UI3 though.
