This looks like a problem I had on my discourse last week. If you create a new poll, does it work? I am not able to replicate now with a new poll on try or my discourse. It seems to work.
I’d love to know the troubleshooting steps for figuring out what’s gone wrong with an existing poll, and to fix it. Broken polls causes alot of anguish in my community.
We really need help with polls not working. As for our community voting is at its core. And now all of the past votes we have created since 2016 don’t work!
