From some of the Convo’s I’ve had with the premium team - It has been beta tested by staff internally - a bug was found, that meant that existing bookings and bookings make on the legacy website were not being carried over to the new app; so that’s been a bit of a stumbling block, which I believe has been fixed.
They honestly should let some GGLs just beta test it - we would be able to run the app through as much as possible and report issues faster than internal colleagues who don’t fly.
