My Verification status is "Legacy" - limited to 2,000 USD.
I tried several times to verify for the next level. I keyed in all data, uploaded all ID photo etc. By now there was no information on the website (or in an email) like "Verification pending".
Is this normal?
I still see the form where I can key in my data. If I do so I am just getting the message "You must wait at least 3 days to re-verify your profile."
Yes this is normal. Give it time for them to verify the submitted information. I haven't done Poloniex's verification, but I did do Bittrex's. They managed to verify it within a matter of hours after sending in the proper documents. This hasn't been the story with everyone else though.
