Automatically Save

[TrishJ22]

I'm using the Lightroom app on an iPhone and wondering if there's a way to automatically save edits without having to press the icon and press save to camera roll etc? 
Also wondering if it can just save the edited one over the original? Instead of having the original and edited saved. TIA

The changes that you make to the original image are stored immediately when they are made. In Lightroom for the cloud they are stored in a catalog to which you do not have access, but the changes are stored. You cannot save over the original image because Lightroom never makes changes to the original image.

Sorry I should have been a little bit more specific, can they be automatically saved to my camera roll in my phone?

Why would you want to export every single image to the camera roll?
