Postgrain has another dynamic sticker available for scheduling in Stories: the poll! To use it, click on the New Story menu, upload an image and click the stickers icon below the media.
Choose the poll sticker. Now just write a question and the possible poll answers!
Keep in mind: the poll sticker is only available for image scheduling, we are looking forward to include the sticker capabilities in videos as well and hope to do so in the near future.
