To turn this feature off, log in to your Circle Account and navigate to Settings, then to Delayed Withdrawals from the sidebar menu.
Once there, you will be presented with a toggle to turn delayed withdrawals off. When turning off delayed withdrawals, you will need to enter your 2fa code. Once this is complete, there will be a 48-hour period until it is disabled.
By default, this feature will be turned on. Circle recommends you keep this security feature turned on.
