I played this game for quite a while with no issues, but in the last month or so something is different. When I try to zoom in the screen flashes in red and takes away 10-20 seconds from my timer. In the past, I had no issues with zooming whatsoever. I'm doing it the right way as per the instructions. I don't know what happened. But now, it's pretty much impossible to play. Combine that with the increased ads - I'm uninstalling.
