I got the same thing using two different browsers. I filled out a technical problem request with the BBC helpdesk folks. It’s possible this is a problem related to being outside of the UK. Hopefully I’ll hear back from them.

I wished they produced something in Irish that was equivalent to the BBC’s Litir Beag in Scottish Gaelic. That would be brilliant
