Gold Coins for reaching Level 2? (Golden Rainbow)

It said I was going to receive 100 gold coins upon reaching level 2 and I did not, but now that I've reached level 2 it says I will receive 100 gold coins when reaching level 3.

Help?

maybe it takes a certain amount of game time to kick in... i dunno havent reached lvl 2 yet.

Is it your first time of reaching it? If so you should of gotten it.
