Support started to respond faster. But the answers do not solve the problems. Sometimes the impression is that the issues are not read carefully. But there is progress. Circle promises improvement.
You are right, but they seem to be much better than Bittrex at this point, who let their customers deposit and then suddenly denanded ID verifications and freeze funds. Poloniex notified, that they would give a certain date of ID vetifications for old legacy accounts in Quarter 1 2018. This didn't happen yet, so I think, they are still working on their technic of ID verification process.
