We are sorry to hear about this issue.
The reason you are seeing the "User not assigned" error is that your account wasn't fully verified in the system.
This likely happened if you tried to register while the server was undergoing a maintenance update, and your browser cached the incomplete process.
Please try the following steps:
1. Clear your browser cache.
2. Register again using the same email.
3. Enter the 6-digit code on the Confirm Registration popup.
4. Log in again.
Let us know if these steps solve the problem.
Yes, this solved the problem and I was finally able to login to my account.
But registering new accounts with same email address should not be allowed in future, this could be a big security issue for Bridgoro.
I will continue testing exchange to see how everything works and I will post my feedback later, after I get some testnet wallets for other coins.
