Cannot send Crypto from De-fi wallet to Crypto.com app over Solana network

So I made a bit of money on Solana meme coins, transferred it to a stable USDC and have sent it from my Solflare wallet to my De-fi wallet. This has been fine but now attempting to send the remaining USDC to my crypto.com app wallet it never goes through, is this due to high network frequency or do I need to change the coin to a different network in order to send?
