While I agree that it is not supposed to work this way, I have started to habitually call scheduling so I can ask the question. If you are in a rush to sign in for a trip and there is a non-contractual scheduling advisory you have to acknowledge and don’t have time to actually read until after you get to your layover, do you think scheduling is just going to roll over and say that’s okay? If they opted to stiff you for your premiums on changes to a trip more than 36 hours out you are now stuck flying and grieving. If you called and asked (instead of acknowledging the advisement) you would have the option to decline the trip. The current shenanigans have basically made electronic acknowledgment of advisements, inadvisable.
