Attempt to sing up. Email, code - ok. Password: created, retyped, but button is inactive without any clue. Noticed sign: "6-12 characters" (it's not enought... Rrr, but ok, combined). Active button, pressing: "Invalid or incorrect verification code". Mistake in pwd? Ok, retyped it, the same. Realized that email code from previous screen expired (5 minutes passed). Ok, requested and entered new code, retyped password. "Too many request, please try again later". RAGE!!!
