Your bonus tickets are applied to next week's contest, so that you get them for a full week. It wouldn't be as valuable if you got them instantly. You can see the number of bonus tickets you have under "You Have" on the home screen of the app. It should say you have pending tickets. These are your bonus tickets.
Bonus tickets are only one-time so these don't recur in the future.

Note that a referral only counts once the person you referred has made their first deposit, so check to make sure they made a deposit.
