How do I add an option to a poll?
When setting up a poll for the first time, a poll creator can enable the ability for users to add new options to a poll.
Click on the + button in the message toolbar and then click on Create poll with Simple Poll.
After entering your poll information, within the settings section, you'll see an option to Allow options from others by checking this box, other people will be able to add new options to a poll for people to vote on, whilst it's live.
To add further options to a poll after it has been created, use the "Add option" button.
If you can’t see the option, the creator of the poll can enable it.
