Hello

I updated my game and am now unable to buy stuff at the store. I want to buy a mini mix pack but it won't let me. 

i did get my daily gems from the monthly gem pack I bought. I did get the free stuff from the store.

i can battle, chat and do evrything except buy something at the store. I tried other articles and everywhere its the same. I get to wait and a screen with try again/continue appears.
