FWIW, I’m using WP 4.8.1 and WP Statistics 12.3.6.3.
Also, I can’t send a link because this is an in-house installation with no external access.
I was testing the poll and voted. Then I reset the poll. After reset, when I reload the page, I see the results (0/0 for a yes/no vote). I don’t see the poll with the vote button. It appears my vote was cached, although all the votes are cleared from the log. Is there a way to fully reset the poll so it appears new and doesn’t just display the results page?
