I downloaded the new version of Electrum (4.0.2) but forgot to choose/add mining fees when I sent coin to another wallet I have. Now the transaction is in Pending and has been for over half a day. The coin is still showing in my Electrum wallet but I am not sure how - or if - I should reverse/cancel and resend it with fees. What happens if I delete the pending transaction and try again? There are no confirmations showing for the transaction on blockchain.info which makes me wary. The network light is green and I did download from the correct website. I ticked Use Replace-by-Free under Preferences. In version 3.3.8 I knew how to set the mining fee but in this new version it has a new feature - Pay - which is what confused me.
