If you're a new PrizePool depositor, please note that our banking partner has implemented a fraud control that holds new deposits for 5 days from the date of deposit posting to your account. After the 5 day settlement time, your funds can be withdrawn.
Another possible reason for withdrawals not working is if you are a new user and are trying to withdraw more than $2,000 at a time and you haven't been approved for Level 2 Withdrawal limits. Once you have been approved for Level 2 Withdrawal limits, you can withdraw up to $25,000 per day, up to $100,000 per month. See this article for more information around how to apply for Level 2 Withdrawal limits.
