I was trying to list some TF2 items via the app, but when I select various items, it gives this “unauthorized” message every time. The items are all tradable, there’s no steam hold or anything, and I’m not banned, etc. I trade all the time.
I know that months ago, GF removed the TF2 bot selling option, but you could still list manually via the app.
is this a bug, or am I doing something wrong?
