I no longer get AFK protection (since a few days ago) when I have AFK mode enabled for more than a few minutes. I even check it periodically when switching tabs and there’s still no protection enabled.
Edit – I managed to figure out the problem. I was in guild mode for some reason rather than peace mode. I tried changing it before and it wouldn’t let me, possibly due to minor lag. But I guess, you can’t get AFK protection if you’re not in peace mode.
