No 'add certificate' button in apple iOS provisioning portal

Question

I am trying to follow the steps to create a "Distribution provisioning profile". I get here and the instructions tell me to "click the 'Add Certificate' button", but there is no button :-( (nice one apple) I can see from the (similar) unanswered SO question here that others have this problem. I also recall that I have had this problem before, but I can't remember how I solved it. I am using a mac, running safari. How do I get a button? Help!?

Answer 1

I found an answer to this here the key information was "if you already have a certificate, this option will be unavailable as you need only one". Really useful information that.

Answer 2

只有团队代理可以添加分发配置文件，验证您是团队代理，如果您是，我建议您联系Apple。

Answer 3

请注意，在您转到iOS Provisioning Portal>证书>开发选项卡>“如何创建开发证书...”后，“选择文件”命令按钮位于屏幕的底部，并且位于MacBook上....除非向下滚动，否则你无法看到它。
