I can't speak to deposits but XMR withdrawals are currently working. You need to specifically use a standard "old style" address and a 64 character hex string for the payment id. Without either of those the withdraw will fail.
Follow this checklist and most likely your withdrawal will succeed.
SD withdraw checklist
1.Check you have enough xmr balance. Investors need to divest first.
2.Use only basic standard address. No integrated addresses.
3.Payment ID is mandatory. Use a 64 char hex string. If sending to a wallet you control, use this https://www.grc.com/passwords.htm
4.2FA is not optional if you have it set up. Check the time on 2fa device(phone) is correct.
5.If it still fails try a lower amount. The hot wallet may be low or empty. Check the BCT thread.
If you mess up any of these things besides 2fa you will get the same error message as if the hot wallet was empty. When I had the same issue support never responded to me, so yes, the support is dog shit but the site does actually work most of the time as long as you follow the rules (which are stated nowhere and you need to figure out on your own unless someone tells you).
