Support replied that we are checking manually and there is no exact timeframe for checking. I understand that there are no approximate deadlines anywhere? If not, it's really simple, we (players) are 100% in the hands of the casino. If they want to, they will check as much as they want.
I just don't know the exact rules about manual verification when already verified, that's why I asked here. And in general, as far as I remember only from my home ipi or from my mobile I played. I don't use vpn often (although I may have to more often as my country started blocking gaming sites). I mean, I don't think there are any questions about my location.
