Let’s talk about the mempool:
Bitcoin supports Replace-by-Fee (RBF): you can sign a new transaction spending the same inputs with a higher fee to replace one that hasn’t been confirmed yet.
Block space is limited, and miners usually prioritize transactions with higher fee rates. So when the network is congested, transactions with lower fees have to wait longer in the queue.

I get it wrong a lot too—use your own judgment.
