I have identical problem as previous posts, which didn’t seem to get resolved.
I copy & pasted my Bitstamp API key and secret key, however Koinly keeps saying “Access denied, check your API keys”.
I have tried deleting the API in Bitstamp and making a new one and copy/pasting the new keys into Koinly, but the result is the same. For user ID, I tried both by email and User ID. Secret key was activated. What’s the deal? I followed Koinly instructions.
