 After some research, I found a Webkit [post](https://webkit.org/blog/6784/new-video-policies-for-ios/) explaining that video can, under certain rules, be automatically played on iOS. It did not work anyway therefore, I changed the UX on iPhone to start the process only after a user interaction.

At least on her iPad (I did not ask her which version), the share was successfully triggered but, no image was attached to the resulting email. That's why, I also implemented to "old school" download solution for such devices.
