Ah so it's an android bug? I thought the default shutdown was swiping across not a double back button.
It's more related to how Electrum saves the changes. I f it was related to Android, then we would have the same problem with payment requests and created invoices not only deleted invoices.
I may as well just delete my data and start again every time it's potentially easier (only got two wallets).
Do you mean deleting the wallet then recovering it from seed? What I suggested above sound easier since you already have two wallets:
- Open another wallet (supposing you have more than one) then go back to the main one.
Besides, by removing your wallet completely, you will lose all it's meta-data not only invoices.
