It appears that Cryptopia has updated their ZCL wallet, and now have available node connections. However, some pending withdrawals appear to be stuck, and will need to be manually resent by Cryptopia. You may need to submit a ticket in order for this to happen.
If you have more wallet issues, please contact BTCP support and let us know. We are continuing to work with Cryptopia to resolve any potential remaining issues. Thank you for your patience during what would've been a very stressful time for anyone affected.
UPDATE 1: Looks like their wallet is not working again. We will do everything we can to help them resolve the issues.
