Poppins

I have played mini days for several days now and I got so frustrated about unlocking new characters. I reached the requirement to unlock a few characters but nothing happened. I need help, the game is so good but this just makes me sad. Device: IPad Air Ios version: 10.3 Mini dayz version: 1.4

I'm trying to get billy red, Dave boxer and Emilio doc for several games and hope that somehow I will have access to the new characters. I have tried uninstall and reinstall the game but nothing seems to happened and it just made me more frustrated
