As i see, widthdrawals are not working since 2 days ago. I talk about the instant ones, i do not know about the Slow ones (although the countdown is working, some thing that is different from the past times widthdrawals did not work).
Other times have been processed after 3 days more or less.
I'm not saying it works, but did you guys check the state of the blockchain and mempool. I mean, usually these withdrawls are issued with the smallest possible fee, and if BTC price jumps suddenly (like it has in the last few days), your transacrtion, or in this case withdrawl transaction might be waiting for the gas fee to go down to process. Just saying
