very glitchy controls, could not progress

Im playing on a fully updated iPad 2. The controls are glitchy and lag in the mini game to the point of being frustrating. However, the last straw is that on day two after I get the safe code (from the computer crash data), the safe will not let me change any of the numbers (they just remain 0000). Theres clearly a programming glitch on my device where the game doesnt register any taps on the safe. I even tried reinstalling, but no luck. This halts gameplay and is completely unacceptable for a paid game!!
