No. not after receiving feedback.
If You long sell, nothing freezes at all, the money is available immediately. If You have recently sold, then just waiting. If there is confirmation of delivery (according to USPS, UPS or Canada Post), it will defrost faster.
The buyer here does not matter. The buyer can do nothing to leave. As many people do.
