What I noticed playing with mints - too many buttons to press. Opening cashu.me should add a mint automatically. In your vid, scanning the payment should led to automatic reception - delete the extra step / receive button. But I could be wrong… 

 Auto mint selection is a dangerous idea. The developer then may harbor responsibility of the mint's future behavior. A pop-up indicating that the mint is not associated with the wallet may need to be displayed and require user acceptance.
