Hi Colorful Apps,
Prior to the launch of the Dev Center in early August, our commerce team processed a mass payout to all developers with any accrued revenue. For those developers under the $200 minimum threshold, a paper check was sent to the address have on file. If you never received this payment, I ask that you submit a support request so we can get some help from our commerce team and get your payment processed.
