Hey malleman, it typically takes 24-48 hours, but we've been having some technical problems around here when it comes to shop creation. I had trouble creating a shop myself, (the 'submit' button wasn't responding) and when I switched from Chrome to Firefox, it finally worked the way it was supposed to, so you may want to give that a try.
The development team is actually already on it, but If you could give me some details it would actually help them figure out what's wrong faster.
1. Which browsers did you try to create a shop in?
2. Which operating systems are you both running?
3. When did you have this problem?
Thanks and sorry about the trouble. We should have it sorted out soon.
