Coinbase pro to metamask, no matic showing

I added MATIC main net to my metamask wallet. Added wallet address to coinbase, which said it was a valid address. I sent 500 Matic, and it’s not there. Checked etherscan, the transaction says complete. I did not have any ether in my wallet. I thought the transfer from coinbase was the gas charge, but I’m wondering if that was the problem and if there is anything I can do about it? Any help appreciated. PS read a bunch of threads but none seemed to be my situation.
