I have looked on the forum to see if this has already been raised and couldn't fin a topic, however that may be down to poor search skills.
I have tried using the custom poll option to check voter preferences from the previous legislative election and repeatedly come up against an error that the sample size is too small to conduct the poll. Is this a known issue? I used to be able to use custom polls without any issues, so either I've forgotten how to do it, or there is a problem.
