Yes I have!
I had that issue for about 2 weeks, but then finally got an email through to say i've passed the screening and was invited to the Day1 selection event.
What I take from it is that stage 1 is the 'screening' of your application, and the 'awaiting decision' for stage 2 is referring to them deciding whether or not they will invite you to the Day.
Keep patient!
I'm booked for August 23rd
