When I cash out the coins don't increase. Yesterday I had 7 billion coins, I cashed out 4 billion coins but counter remains at 7 billions.
I have a chrome browser and I followed the steps that you suggested going to history and deleting the data and making sure all the Basic steps were checked, then I went off the game, turned the notebook off and came back after a while and still the coin counter was showing 7 billions.
