I had that using my Chromebook. I restarted it and I got a pop-up when I clicked on "Watch live" that I didn't see before. Once I clicked "Agree" it sprang into life. Check you've not got any dialog windows open that are hidden.Screen just buffering for last 10 mins ? Anyone actually got a picture ?
Would have been useful to know in advance about subscribe process and need to enter card details although paying zero! Just had to talk two 80+ year olds through this process one after the other aaaarghIn on Chrome. All good.
The bit that was a little confusing was the need to add a card number to pay zero.
There now anyway.
