Can we get message to confirm that we want to purchase item when we spend Gold (coins) because it is very easy to by accident buy something u don't want. I accidently spent few times in store in last few days for something I dont want. Even for refilling my energy. It is very easy to make mistake, especially if game lags or if u click few times on the screen and then game counts ur previous click for the future and buy something u dont want and things like that.
It is not that hard to implement system message where it asks you to confirm that you want to spend your gold.
