Use store apps! But make them better
A few complaints:
1) there’s a bug in the app when you try to create an account where your phone may automatically enter your email address in the phone number field. Once the email address is entered, it is impossible to delete it.
2) if you have a pre-existing account, make sure you login before ordering. Once I logged in it kicked every item out of my cart.
3) despite having issue with the email auto filling in the phone number field, most of the fields in the app do not support smart filling in iOS. (It wouldn’t autocomplete my email address, phone number or credit card info)
4) it doesn’t support Apple Pay.
