I made an eth deposit some time ago. Multiple people seem to be having this issue as well. Everyone is being told to "wait for an admin" or that it's being worked on, however, I noticed posts about this same issue detailing a problem that's been ongoing for weeks now. Deposit at your own risk as apparently, a few have been waiting for days.
I guess may-be deposits from the contract address need to process manually. (it is a little bit difficult to detect deposits from the contract-address for ETH)
