Can't withdraw Toncoin despite meeting minimum — likely fee or hold issue

I'm trying to withdraw Toncoin but can't, even though my balance is 0.066 TON and the stated minimum withdrawal is 0.051 TON.

Most likely the platform's minimum is checked after subtracting the withdrawal fee, or there's a temporary hold/KYC/maintenance or a network/address mismatch that makes 0.066 effectively insufficient.

I need to verify the fee, the required post-fee minimum, any pending holds, and contact the platform's support with screenshots if the problem persists.
