I have a question myself. When I go to settings, it appears as though some options are missing. Battery saver can only be accessed if I search for it (it's nowhere to be found under Battery settings). Also, I cannot customize the ambient display setting, it's also nowhere to be found under display settings. I want to have a custom image on my lock screen, not the album art over the whole background.
In terms of the lock screen artwork, it has nothing to do with the Mango App settings. I do have ambient mode on the Mango App, and I also tried the normal mode — neither have any effect on the lock screen; only the in-app background. Also, I have "Lock Screen Artwork" set to Off. I do vividly remember that you could change the ambient display under display settings (you could set your own custom image). In fact, it pops up when you search for it, but you cannot customize anything.
I am running the latest version (which was updated over the Updated in settings): 1.03.241
