The REWARD in RED CHEST did NOT APPEAR on screen!

i was thrilled about the new update so i jumped into the game to see what is new... I headed to town hall even played the portal game to aquire about 30 rainbow stars payed (through the seagull) for the rest as i wanted to open the 50 RAINBOW STAR CHEST and when i FINALLY opened it i either did not receive anything OR it DID NOT SHOW UP... I would like to know what the actual reward is and how to check if i ACTUALLY GOT IT. Thank you in advance for your time!
