"I sent a transaction from the wallet to an address. Later that day I sent another transaction to the same address (while the first transaction was still unconfirmed). The second transaction re-used a txo from the first transaction, cancelling the first transaction (RBF). The recipient only received one payment, not the required two payments."
Could you please check this scenario if it still relevant?
