Themes are backwards
I think this is an iOS bug, but suppose it could be a server issue. I don't have an Android device to test.
Essentially, the iOS remote displays a custom light theme (as specified in a layout.xml) when the iOS app is set to dark, and vice versa.
Also, I find it strange that both dark and light tags must be defined in the layout.xml in order for one to be recognized. I only make dark themes, but need to add a dummy light tag (actually a dummy dark tag, since the themes are reversed). I suppose this might have been a design decision but would prefer that default colors would simply be used if only one theme is defined.
