I think I remember some old discussions on this forum about WB21 being a scam that never allowed it’s users to withdraw their funds. (perhaps it was this one Does anybody has experience with: https://www.wb21.com )
Anyway, I thought that scam was dead now and everyone just accepted their loses if that was the case.
I don’t think that there are many Bisq users that use that “bank” here, so I don’t think there is much use of posting about it here.
