Anyone experiencing this and is there a fix or a setting I need to change as I look into all and nothing helps.
I can't reproduce this in v4.3.2, I'm always getting a new or unused address in every request.
Now, the wallet repeats past addresses on new requests and in order to get a new unique one I need to open like 4 of 5 requests until a new address is given and also once payment is received on history it does not show the label I created for that transfer.
Was the gap between those requests more than 10 minutes and your invoice's expiration is set to 10 minutes?
If so, it will reuse the addresses of those old expired invoice as long as the address didn't received BTC yet.
For the label, if the invoice was expired or the amount wasn't fulfilled, the label wont be saved to the history since Electrum it didn't matched the invoice.
