It depends...
It depends with a TSC's officer mood whether he/she wants to change your LUD or not. Mine didn't change until a month after I did my FP. Well, the date changed but the message remained the same like "The document we based...." But maybe you're lucky like the other members here, their LUD would change consistenly after some activity with their application. Well, always hope for the best. They say that after FP comes approval. Good luck!
