If you're not already connected to the PLAYA3ULL Mainnet in MetaMask, look for an icon in the top-right corner of the dApp. Clicking this icon will prompt you to add the PLAYA3ULL Mainnet to your MetaMask and switch to this new network.
Verify the network information in the add network prompt is correct and proceed.
