Just heard about app.teslatv.co.uk today and been trying it in my 3.
Nice interface and layout, full screen click through works perfectly opening in YouTube.
Geolocation option didn't seem to work for me, just displayed an empty box.
I wonder if worth removing the Netflix and YouTube options and replacing with Disney+ and BritBox? (looking at requests so far)
iPlayer, Plex, 4od, My 5 working fine for me. Can't get Amazon Prime video to work though - says unsupported browser. Anyone had any luck getting it to work?
