In order for TrueSteamAchievements to track your games and achievements correctly, it is required that we have access to your achievements. If your achievements are not being scanned in, it is likely that your privacy settings are not allowing this. To correct this, please follow these instructions:
1. Log into https://store.steampowered.com/
2. Click on Edit profile from your View Profile page
3. Select the Privacy Settings option and change your privacy state to public.
These steps will allow TrueSteamAchievements to update all of your achievements across all Steam platforms.
