Microsoft recently released an update for Whiteboard app in Apple App Store. This update comes with a lot of exciting improvements.
Microsoft has added new highlighter color and thickness options that will help you emphasize your content. Selection visual improvements make it much more obvious what content is selected. With this update, meetings now appear as suggested contacts so you can invite all participants with a single tap. Finally, education customers can now see the send to OneNote menus in an easy to use side panel.
You can download the updated app here from App Store.
