So, first YouTube bug? It was working fine earlier, I signed in with my google account, set up 2 connected devices, watched a video. Now, whenever I try to launch YouTube, it displays the YouTube logo and just sits there, the app never actually opens.
NB, the box remains fully responsive, I can exit via the remote, switch to another channel, etc, the box is not hanging. NB also that my network connection is absolutely fine - I can immediately get iplayer up, for example and that app works just fine.
I've rebooted etc, to no avail.
Any ideas? Launch day teething problems?
