Hi 
So, basically since I installed the game I couldn’t find the Overwatch folder in C:\Users…\Documents. At first it didn’t bother me that much, because the only downside I saw to that is that I couldn’t save my highlights. But now I want to change my graphics settings and it wouldn’t let me (I press “Apply” and it doesn’t do anything), so after looking in the forums for an answer I couldn’t find, I decided to post my own.
Edit:
I’ll add that it might very well be because I have OneDrive installed (and Windows 10 being Windows 10, my Documents folder is automatically in OneDrive). If there was a way to change the location of the Overwatch folder it’ll easily solve my issue.
