If you are only able to delay one turn, you are doing something wrong. I've done it for days at a time with my army to great effect.
Similarly, Port Nebel has just revolted to Corsanctum again. However, last I checked, they hated that realm more than anything in the world. Well, them and a few others.
The new delay arrival button only works once, of course you can still use all the old delay methods, but you can't press that button two turns in a row.
