Otherwise, does it help to move accountDataDB.package out of Documents > Electronic Arts > The Sims 4? Do NOT delete this file, which holds the data from the first login rewards event; just move it, temporarily, somewhere else. Then load your save again, or start a new one, and let the game clock run until (if) you get the event-related pop-up, which does take a bit of time.
