Was able to find the reason for the issue: When setting up the app, after giving Winston permission to use the Reddit API Key (the screen where it shows "open winston" or "go to winston" afterward I don't remember exactly) it will start the app and show an "everything set up" screen. If the app crashes at that point and will be started manually afterward, the issue like I described above will show up. If the app doesn't crash at that point, everything will be set up correctly and there are no issues.

In my case, the app crashed at that point because my Pi-Hole prevented it from loading something, so it never reached the "everything set up" screen. After starting the app again it didn't try to load again whatever it tried loading before (even without Pi-Hole), so it seems like the set-up process wasn't finished, but winston doesn't realize that the setup process was not finished completely, so the error occurs.

Yeah Winston currently doesn't actually check if the API key actually works or is set correctly and it will always say that everything is working. This is definitely something we should fix @Kinark.
