Informational footers appear at the end of every Sway to help your viewers create their own Sways, quickly share yours on social media, or get a link to send over email.
Office 365 subscribers across our business, education, and consumer offerings can remove the footer by signing into their account and following these steps:
Click on the Share icon on the top navigation bar of your Sway.
On the menu that appears, click More options and uncheck Show Sway branding in this Sway.
Click Play on the top navigation bar, and you and your viewers can now see your Sway without the informational footer.
