Solana Coinbase Wallet - Testnet

Hi, I am in the process of trying to complete some testing for the Solana network. I see Coinbase has Solana support, but it appears to me the Devnet/Testnet is not working correctly.

When I got from Testnets → SOL → Receive, the address I see begins with 0x and its showing my ETH based address.

And then also since I cannot test this just yet, will the wallet show USDC balances similar to what we see on the EVM compatible chains?
