Did not receive Rainbow Drop Acquired Emote

I played the UQ required for it at 7AM (GMT) on 5/5 but I didn't get the emote at the Visiphone afterwards.

The 3rd campaign/event started at 8 pm GMT. If you look at the description at the time and day closely you will see that it started at a much later time.
