No option for Ackbar Fleet Commander Training in Events

under solo events I never had the option for Ackbar’s Fleet Commander Training. I’m level 39. My son had it appear today for him. I’ve tried uninstalling and reinstalling the game but that did not help. My ally code is 512-933-533. I need to complete this event to move on in the game. How do I get it to appear in my Solo Events?
