Based on how many people have complained about similar service-related issues, I would guess that CX isn't unaware of the problem - rather there is nothing much they can do about it now. There's only so much training you can do, a lot of it comes from real life experience... unfortunately while new crew could be eased in in the past, that is no longer the case.

We can only hope that it will get better as time goes on, can only wait for this transition phase to be over with.
