I initiated small withdrawal yesterday, it has been approved and processed but you've sent it with fee of ~45 sat/B, while recommended fee is currently 600 sat/B.
Do you have any policy in place to rebroadcast the tx with a higher fee if it doesn't get confirm within certain time?
From my experience, they always processed the withdrawal with small fee and it always take pretty much time just to get your coin here. With this current traffic on blockchain I believe you should wait longer time to get your money as well. As you can see they got pretty huge red trust right now and I do not think that they have any of this policy to make surr your money comes to your wallet. The only way is just wait them to confirm your withdrawal process
