The problem
We know that sharing across devices is really common, especially for professionals planning out a lesson about a specific subject, and users that interact with multiple devices throughout the day.
We heard from our users that unstable or non-existent WiFi connections were a huge issue for sharing in schools. While we already had some sharing options available, not everyone has a Dropbox or Google account or wants to make one just for this situation. We can also imagine that someone who needs to share materials across a large number of devices wants to find the quickest and easiest way to do so.
