What does excluding an "album on device" actually do?
I'm sure I'm missing something obvious, but what does double tapping an album on the Android app actually do? I have a variety of albums listed, like Camera, Screenshots, WhatsApp Images, etc, but doesn't it only back up what I've selected to include? I.e., if I check "camera" and leave everything unmarked, it will only back up images in the Camera album. Why would I want to explicitly exclude some other path?
