Opensea / Selling

Hello,

I’m having a massive headache simply trying to sell an piece of work on OpenSea via Metamask as the wallet. It keeps telling me I don’t have sufficient ‘gas fee’s’ every time I try to sell and initialise my wallet despite their being $300.00+ worth of ETH/WETH on the balance.

Can anyone help? totally confused here. I have a video showing what the issue is but I can’t upload here sadly.

Thanks,

Michael
