Cryptos not in Metamask

Transferred ETH to Uniswap to buy crypto tokens to add to MetaMask wallet. ETH was swapped but not found in MetaMask account1. Account1 unable to add tokens to MetaMask. Unable to add custom tokens. Under assets no tokens, only remaining ETH from cold wallet no longer connected. Downloaded transactions appears to show swap. How do I add these tokens to MetaMask wallet?

What error do you receive when you attempt to add a custom token?
