I also trying to send with armory 0.96 and Bitcoin core 14.1 since two weeks. I used several times the delete all unconfirmed function to resend with higher transaction fees (already reached 500 satoshis/byte) from 2 different wallets and with exception of one time, where I had a double spend transaction, which showed up at blockchain.info, the transactions did not even show up at blockchain.info. How can I find out if the transactions are send correctly to the network? Should it immediately appear at blockchain.info with a fee > 360 satoshis/byte?
