Booking appointment at premium service centre

[Pthaveel13]

Hi, I’ve been trying to book the appointment for ILR at the premium service centre for one day decision on Home Office website. However, when I get to the ‘choose an appointment’ page and selected the date which says ‘available appointments from the date selected’ I can’t continue to the next step. There is a red box saying ‘you must answer this question to continue’ However, the ‘you must answer this question to continue’ link is not clickable and there is actually no question. I don’t know what to do. Been refreshing the booking page the whole day and very frustrating! Does anyone come across this?
