Coinbase Wallet Adding ETH and Polygon “Failed to persist wallets”

Just grabbed an account and tried adding ETH separately then deleted it. Tried to re add the same wallet since I also utilized as Polygon. Gave me a Failed to persist wallets message. Also when I tried to add two coins such as ETH and Polygon it only gives me tax info for one not the other.

Guess theres no layer 2 thought behind the same wallet address?
