Super priority service for SET(M)

Hello,

I am ready to submit SET(M) application online for my wife but on the payment page I do not see an option for super priority service. It gives me an option only for standard service fee. From gov.uk I thought that super priority service is now available for SET(M) application inside the UK. Is anyone facing same problem or has any one got an option for super priority service with SET(M) recently after the update on gov.uk?

Keep checking through out the day especially after 1AM BST at night. It looks like there are a few slots released every day on first come first serve basis. Many members have reported the same but some were successful with hit and trial.
