KuCoin may have changed the format of their CSV and new imports fail.
These are error messages that have been reported when attempting to add KuCoin accounts to CoinTracker:
"Failed to add account. Either the values below are incorrect, or the Kucoin API is currently down."
"Failed to parse CSV. The CSV does not have the right headers in the first row. Headers should be Date, Received Quantity, Received Currency, Sent Quantity, Sent Currency."
A workaround is to convert your KuCoin CSV to the CoinTracker CSV format and use that method of import instead. Please see this article for instructions: https://help.cointracker.io/en/articles/5172429-converting-transaction-history-csvs-to-the-cointracker-csv-format
