Number of participants in poll reached

A poll I made had the number of participants reached. I just updated my pollunit account to be the lowest paid tier, so I ought to be able to have more participants. How do I update the poll as such?

When you create a poll as guest and when you did not add your (or a different) email address to the poll we can not automatically assign the poll to your account. Please login and visit the admin link of your poll. Then you can take ownership. If you have problems taking the owner ship, please reach out to support@pollunit.com with your account email address and the admin link. Then we can help.
