Fill it in. Your own code is made when you pay.
Give one or both store links. A phone is sent to its own store. Anything else sees both links, or goes to your web link if you add one.
Shown when both links are offered. e.g. Fennel Street Orders
e.g. https://apps.apple.com/app/id123456789
e.g. https://play.google.com/store/apps/details?id=com.example
Computers go here instead of the page with both buttons, and so does a phone whose store link you left out. Many iPads tell websites they are a Mac, so they go here too. e.g. https://example.com/app
Pick a different kind of code
