I am waiting for it too
In the morning on 4/4 I did FP. LUD changed 4/4 (afternoon) and 4/5. Then no message changes at all.
I have a friend who did FP on 3/15, but so far she has no message change yet. Message change to resume the case is supposed to happen with 2 weeks after FP is done. Keep us informed when you have any update.
