I have enough ETH in my wallet but cannot purchase.

If you can't purchase despite having enough ETH, consider the following:

1. You may not have the required tokens.
   1. If your ETH (WETH) is on a blockchain other than the Polygon PoS chain, you'll need to bridge it.
   2. Use the Polygon Bridge to bridge ETH to the Polygon network.
      
      
2. The Polygon network may be congested.
   Consider the following actions:
   1. Adjust the gas fee settings in MetaMask.
   2. Please note that changing settings may increase gas fees, so adjust them at your discretion.
      Try again during a time when the network is less congested.
