So before I found out about the app, I used to just download the games and installed them into a folder on an external drive. Said folder has a bunch of subfolders so that I could sort the games by genre and such.

Anyway, I just downloaded the app and set that folder up as the install location, and used "scan install locations for apps". But the app can't seem to find the games installed there. The same is the case when I set one of the subfolders as the install location, and even with the game folders themselves.

Am I missing something?
