The option to cancel is removed temporarily, but even if it were there you can't cancel payouts that are processing (the orange ones.) If it gets stuck orange for more than a few minutes (max 5 minutes) it means we received a successful transaction in the API but PayPal ultimately refused the payout.
The most common reasons for a payout being refused by PayPal are account limitations or sanctions affecting the country the PayPal account was registered in. In any case, please reach out to us so we can help resolve this for you. https://codefling.com/help
