I would like to avoid the (currently) high fees involved in sending between addresses, if possible.
If you are not in a hurry, then you don't need to pay those fees. Just send at 1 sat/vbyte and be prepared to wait.
I see this option was kind of hidden. If it's set too low doesn't the transaction risk getting rejected or lost in the backlog?
The Max button is definitely not working for me.
There must be a valid address in the "Pay to" box before the "Max" button will work.
Ah ok that makes sense.
It also was not obvious the request (B) button had to be pressed to populate the address area.
I'm probably a bit dyslexic with UI, and this one is very unintuitive!
Also the copy and paste address functionality is not working at all between wallets.
Very strange. Does it work within a single wallet? If you hit copy on an address from the "Addresses" tab, can you paste it in to the "Pay to" box on the "Send" tab? Is your clipboard working normally for other programs?
This GUI is so confusing here. I now have an outgoing payment that appears, and has been 'pending' for about 12 hours.
I set the rate to about 20 sat/vbyte
Does this mean the payment is still queued and / or the network is congested?
What happens when the receiving wallet time window expires in another 12 hours?
I did not verify the download as suggested in that link, but I always go directly to electrum.org and download from there.
I know about the popup scam and would avoid Github for this too.
