LINE is an application that runs on Windows, Android, iOS. LINE has no web UI, nothing at all, in fact its website only shows static help pages. If you don't own a smartphone with a phone number you have no way to use the app, that's how it is designed.
So, when I asked a question about LINE, I hesitated between Super User and Android, finally opting for the latter because my question is about the interaction between the Android app and the desktop computer app.
I was quite surprised to discover that my question got migrated to Web Apps, the most unlikely place for it.
Is it just a judgement error? Or am I missing some information?
