Fullscreen not working on Ios Devices

Hi, i’ve noticed that the fullscreen button is not showing up on ios devices regardless of the browser used (I’ve tried on iphones 6-7-8 and on 2017-2018 ipads using safari, chrome and mozilla). I thought that it maybe was a mobile problem but it shows up and works fine on android (and also on pc/mac).
I’m using the latest version of the plugin (1.4.1)

Is this a problem on my end or is this some sort of compatibility issue with ios devices?
