Adding Polls

I want to add some polls to my WordPress sites. So I began searching for scripts until I discovered that Polldaddy is already included in WordPress, according to this page: https://en.support.wordpress.com/polls/

But I don’t see anything relevant listed in my dashboard @ Feedback > Polls

Am I missing something, or do I need to install a special Polldaddy plugin after all? Or are there better or more popular polls I should be considering?

Thanks.
