I just created an invoice on another wallet and pasted under bitcoin section. It gave me the opportunity to chose. I communicated with miles, that the option to paste a lightning invoice should be available under the $ tab, which is essentially the hone screen. When you bring up that scanner, paste isn't an option.
Maybe one day they'll give the receiver the ability to decide how they want to accept their payments, regardless of how the payer chooses to initiate the payment
