isn't the dinamic fee the one that is labelled as a "recommended" on core? so this is not something new if this the case, but i admit i was not using it, i prefer to set it to 10k satoshi and forget
Same here, I am not using it and don't need it. I nowadays include a fee of minimum 0.0002BTC for each transaction that I send. It works perfectly fine as my transactions mostly get included in the next block.
