The invitation is four letters, not a link

A URL only opens the installed app on Android; on an iPhone it opened a second
copy of the game in Safari, with its own storage and none of the name picked in
the app. So the share sheet now sends "JOIN ME IN SPLATTER TENNIS — THE CODE IS
ABCD" and nothing else, and the button says SEND THE CODE.

The #net-ABCD door stays — it is exactly what a deep link will carry the day
this is a real app with universal links. Nothing sends it in the meantime.
