I did that, for now 5 hours with 0 confirmations.
Can you help me to set up fee slider for next transactions?
I'm not sure how you'd do it on the newer version of electrum in order to set upthe fee slider to wrok better.
However, if you set the transaction fee to be a set amount per KB then the amount you need to set is around 0.0005
BTC per KB.
That'd be for a fairly quick conformation (one in a few blocks - 60 mins max).
Unless you uncheck and recheck the dynamic fee settings or move the slider back to it's original point. You could also try reinstalling the software (or just wait to see if a more advanced member who can navigate the software better sees your post).
