Some of our shows are in SUCH high demand, we have set a limit to the number of submissions you can have requested at a time. This allows the waitlists for the shows to be smaller, which makes it more likely that your request could be approved.
This is of course not a guarantee that your request gets approved, since we have to take more requests than we have space. When shows are popular, people who receive tickets are not as likely to decline them.
It can help to be following our social platforms to be kept up-to-date when more shows are posted.
