I think now a days there is too much traffic in the withdrawal section of FJ and recently there is a rumor happens that database of FJ was havked so now the support team is very careful that the owner of the fund is withdrawing or not so sometimes you need to confirm your email to withdraw funds and in that case you need three days of time to receive your funds.Or you may withdrew amounts recently from different IP address that is why they want to confirm I think.
But it will be more better if you contact the support team at discord because where you can get instant replies,hope your problem will be resolved soon mate.
