Start off by saying this. I read other posts in this forum, and noticed that setting the default dynamic fee (.0005 btc/kb) is not nearly enough to confirm in a timely fashion. So I understand why it didn't confirm, and that I pretty much can't do anything about it at this point except wait for the transaction to become inactive and the funds are released.
That being said, I notice that dynamic fees only go up to .001 btc/kb, where I've read that the recommended fee is .001 to .0011. Is there a way to increase the fee slider past .001?
Go to Electrum/Tools/Preferences/Fees and untick the Dynamic fees, you will see that the transaction fee for Kb small window will become active.
Put 0.002 for fee for KB/transaction. That should solve your problem, although I agree with kolloh setting the dynamic fee to the far right is the best way and you will not have problems with transactions confirmation speed.
