why aren't the buttons to get processing power and download bots doing anything?
If you're having the same problem as me, it's because the prominent number at the top of the screen is not how much currency you have, but your lifetime total — your current purchasing power is displayed below the buttons at the bottom of the screen. (in my case it was scrolled off the screen and I didn't realize for several minutes)
But maybe that's not the issue you were having, in which case, no idea!
