Apple's buttons are well displayed, yet once i created an account and confirmed all emails and what not - it still won't let me to download damn free app, claiming that i "have't used my new account at store yet". I am ok with small buttons as long as they work. Make sure your backend actually works from this point on, not like apple's piece of crap they couldn't put together.
