Hello, I sent 900 DAO and 1000 USDC over ERC-20 network to Gate. io via my Metamask wallet. DAOs arrived but USDCs did not. It appears to have been transmitted according to Etherscan records. However, the USDCs did not arrive in the Gate. io wallet. I also reported the situation to Gate. io. My 1000 USDC investment was lost. On Metamask, the transfer was successful, but the balance was not transferred to the USDC wallet on Gate. io. Can you help me on this issue? Thanks.
