Are you saying it's not possible to use the "decrease payment' option when bumping the fee at all?
As long as the replacement transaction is valid and meets nodes policy rules (including BIP125 requirement), the server should accept the transaction and broadcast it.
Exactly that is what I mean
, but maybe. Maybe I am wrong because I use the testnet
, but not likely. I will later try it on the mainet to know if it will work or not.
But the testnet has always been like the mainet in everything that I have tested before which is the reason I use it to explain something like this.
