Hey, we have added switch network. Next time you see the Wrong Network warning you can click Switch Network to connect to the correct network.

Hey Martin, the Exchange must be connected with the BNB testnet network as it is not yet live on the mainnet. If you try it with BNB mainnet network you will get the notification "wrong network". If you need help to add testnet to Metamask, take a look here: https://docs.palmswap.org/beginners/trade-on-testnet#connect-metamask-to-bsc-testnet
