Hello, I'm pretty sure i'm doing something stupid but I cannot figure out how to get Big Box to just boot into the Theme I just downloaded and applied to every instance. I select the theme I have downloaded Unified and ultrawide and apply it to each console I have games for and apply as the main theme and then exit Big Box. Once I restart the same default theme loads in Big Box. LIke I said I'm sure it's something simple.
