I tried a second registration after about 7 days as I wondered if I had a problem with the email. I used the same user name.but a different email and phone. I gave up when I hadn't heard anything, and then suddenly I got emails for both applications within a few minutes. I only used one of course. It must have been getting on for 3 weeks before I got a reply to the first one.

I suspect they are getting a lot of applications, and they are batching the processing. I guess the answer is to be patient for another week or so.
