I'm using Wallet Connect
I think what @Bitcoin_Arena means is the wallet interface you are using to manage your ERC20 token not the function that can be found on UNISWAP for connecting your wallet. If however you are using metamask as an extension to your browser. After loggin in, you can easily spot your wallet logo at the top right corner of the extension. Go to
Settings --> Advanced --> Advance gas controls (set to ON)The only problem when using UNISWAP is actually the expensive transaction due to the small cap projects that polute the entire Ethereum network causing a massive network congestion which result to an expensive transaction fee especially if there is GAS war happening. Just a tip though, in my experience, if you really want your transaction to be broadcasted quickly, you need to have at least 10 USD equivalent amount of ETH in your wallet in order to avoid "failed" or "reverted" transaction due to low gas price. It'll cost you more if ever your transaction gets stuck and eventually failed since the gas fee you've paid will never be refunded.
