Returning Player

Hey guys, returning player here. I noticed that there's this returnee event that includes the supply crates and the missions, but I can't figure out how to get the coupons for the limited supply. I'm assuming this is because the event only applies to Returnees that came back before Dec. 5? Also not sure if the event refreshes immediately after this one is over on Jan. 4.?

It would suck if I were "welcomed" back into the game by not being able to do any of the returnee stuff that I should be able to do.
