Good Day Team

I live in South Africa and received an e-mail granting me access to the beta version of Primal Legends. Thank you for selecting me.
I have tried to download the game but i cannot. i have tried on android 4.4.2 and android 5.0.2 and it is not downloading. I was looking forward to the game as well as the rewards for Mgg and Primal Legends. Please Help.
