This post is about RECEIVING BTC. No slider. No control... 6 days and counting
I love the wallet, but I cannot work with this.
Again, BTC sent from the SAME sender to another address confirmed in hours....
That's like saying your letterbox is faulty because someone sent you a parcel with insufficient postage and the Post Office delayed it.
You do realise that the RECEIVING wallet has absolutely NO control over the fees right?

If the transaction was sent with a low fee, blame the sender... they're the one who set the transaction up and set it with a low fee. As a receiver, the ONLY recourse you have is to attempt a "Child Pays For Parent".
This is NOT an issue with Electrum.
