The new mechanism that already implemented when london hardfork happened didn't meet our expectation and it was even making the transaction fees become even bigger from day to the another day. It never goes down again since london hardfork already implemented. If you're using the lowest gwei to send the transaction and then you will not be putting into the priority transaction by the block. Adding 2 more gwei means nothing and what you need to do to use the average gwei ( medium - high) instead of using low gwei because low gwei will make your transaction gets stuck until the gwei will be going down to touch your your transaction.
That's why try to put medium - high gwei instead if wasting your fees to speed up or cancel your transaction. You need to add more money to make your transaction to be delivered and this is the best choice.
When you're using low gwei for your transaction and that means you're wasting your money and your time. This is the worst thing from ethereum blockchain.
