Why does skydemon sometimes ask for a login password and other times not?  Annoying one today when I was trying to use it on my phone in flight but it needed a log-on and faceid did not work with headset, sunglasses, etc on.

Windows laptops/desktops have their own maximum of two devices, so shouldn’t consume a tablet/phone one. Even a Silicon MacBook running the mobile version of SD cleverly uses a desktop licence.
