Dorico SE / iPad without Internet?

I tried to get some notation done on the plane but Dorico just winked out of existence, presumably because I had no internet connection for the licensing verification. Is this a correct assumption? Does Dorico only work if you’re online?

It’s certainly not as clear cut as that - I’ve successfully used both Dorico 4 and the iPad version on planes and ships with no internet connection.

Activating the licence on the desktop is a one-time deal, you don’t need any internet connection to use Dorico on the desktop once it’s done.

The ipad version, once downloaded, should also work fine (though if you’re using cloud file storage, you’ll need a connection for that.
