Is there a way to change background color on mobile app on ios? Not of the actual photo but the color boarder behind it. On the laptop this is done with a right click to the area around the photo being adjusted and I can set it to white. Is there a similar option on the phone?
Unfortunately, it is not possible for both platforms (ios/android) to changing the background colour. You can do a feature request for the same, here: Feature Request/Bug Report Form
