No, you do not need to reverify. You can always check using chatbot (by sending "hi") how much is linked and estimation of recieved coins.
thanks for the info.
However, I do see a discrepancy in amounts linked to my BTC address. I've actually added more BTC to a few of my addresses, but it's not showing up when checking by using "hi." Are these addresses rechecked by byteball prior to actual distribution to get correct amount of BTC?
