You can add a poll to a thread post by clicking the button to the left of the paperclip icon.
Type the poll question in the body of the post, and then type in the list of options. Note: Only 5 options can be added.
To create an anonymous poll, click the Anonymous Poll button.
If you’re unable to view poll results on mobile, it's likely because you haven't voted yet. On mobile devices the "view results" link will only appear after you've voted in the poll.
What to Do:
Make sure you’ve voted in the poll.
After voting, the "view results" link should become visible, allowing you to see the poll results.
