It's been 48 hours now and the description still reads "unpaid".
Do you see this on the
Send tab?
If Electrum-RVN works the same way as the original Electrum (which I suppose it does) then you will see the
unpaid status only when you try to send coins but click on "save" instead of "pay". This will save the transaction as invoice instead of broadcasting the transaction. To solve this (assuming you still want to send the coins to the same address), right click on the transaction then click "pay".
Nothing is showing in Ledger Live.
Am not a Ledger user but according to
Ledger support "RVN accounts cannot be added to Ledger Live". So, nothing will show up on Ledger Live, you have to use Electrum-RVN to manage your coins and monitor your balance.
History tab show the amount and the green button is, well, green.
If the funding transaction appears on the
History tab and the coins were added to your account' balance then you should be able to spend them.
