Why can't I play Interactr fullscreen
Currently, it's not an option to play Interactr in fullscreen mode due to the limitations of mobile browsers not allowing the use of a fullscreen video player. We would like to keep the mobile and desktop experience as seamless as possible so if something can't be supported on mobile we will not currently add this to the app.
However, if you want to play it at the full width of your screen if you set the width really high (3000px) it will automatically adjust the size if the browser is smaller than 3000px.
