During this hold period, it is possible to remove the address from your Address book by hovering over the address and selecting the trash icon
After the 48-hour hold period ends you will be able to withdraw crypto to the newly whitelisted addresses. As this is a security feature, you may not withdraw crypto to these pending this addresses during the 48-hour hold period.
