I could not register with my email address as it said undefined??? For some reason Apple Pay would not work either. Thankfully registering with Facebook seemed to eork. Also both my partner and I could not book a free standing ticket for the bbc concert orchestra on Thursday . It kept hanging at the processing stage for both of us. Finally we could not order tickets for more than one event at s time. And had to buy bbc and Liam Gallagher tickets separately . Maybe bbc had run out of standing tickets but it should have said so. Finally it never remembered my card details and I had to keep changing my phone number as Facebook had my old one. Apart from that :)
